Both have similar miles and are about the same price. All other factors are relatively the same(as similar as two used cars can be that is). Same color too

modded gt would be at the upper end of the market price and the GXP would be at the lower end. That's how the prices can come close to approaching each other.

Modded GT is pretty modded. Headers, wheels, interior, tune etc.... GXP is bone stock.

gxp easily

That honestly doesn't sound very modded, unless you are leaving out alot. I guess it depends on your long term goals. To me it would take a heavily modded Gt thats done and doesn't need any additional work, to buy over a Gxp.

sway bars too. Plus alot of interior stuff. But stock cam, dod equipped, stock heads. Longblock untouched.

I think "heavily" modded to you would have to include cam, dod-delete, high stall. Basically like your sig. haha.

Do you realize how much more rare a GXP is?

I understand the differences in terms of rarity, performance at stock levels, better brakes, better motor, 3.27 rear etc, etc..

Just wanted to read other people's opinions.

well there you go

I assume you mean to pick the GXP. But rarity is the only factor in your choice?

Unless you want a Stealth, GXP wins.

It really depends on how you plan to use the car. If the GXP is a manual, and you prefer a manual, then that is the only way to go. The GT, especially modded, will perform close to the stock GXP. If both cars are automatics, then it comes down to what do you want.

Value is relative. If speed is important to you, you can generally find a modded gt that's much faster than a similarly priced gxp everything else being equal. If you value rarity then go for the gxp. If you want a stick, then the choice is obvious. If you want an intact warranty and you don't plan to mod, go for the gxp.

Hi there :)

Get the GXP.

There was a white hot GXP auto for sale at just under $28k. About 37,000 miles.

It sold faster than the time it takes one to reach 60 mph. Congrats on the lucky owner. But this was an interesting topic and thanks for the replies. It's still very valid info regardless.

I don't even consider my performance mods as 'heavily'. My appearance is heavily modded though, lol. Sounds like a Gxp would be better off for you especially long term and resale. I bought the Gt since I knew I could do alot of mods for the same price as a stock Gxp. I personally consider my car a bit more rare than a Gxp, IMO.

For the extra cheese spent on the GXP, you could get a turbo or SC and get a hell of a lot more HP out of it than going with a stock GXP.

I couldn't justify the price difference for lower gas mileage. I like what the GT offers and I don't really care about being the fastest on the street. However, I still like owning a car that can outrun most cars on the street though.:driving:.

Gxp!

OG reunion! When you heading back to Charlotte? I need to drive one of these things haha.

Once I run my 9 I may sell the beast for 40k$. Save up some more and buy it lol. Will have a brand new 420ci motor.

Had a 335i for a while but sold it a few months ago. Now we just have an Acadia and a Solara (wifes car). Looking to get another "fun" car.

Cool.

This car is definitely quick. I've had mine for almost a year and it still amazes me how fast this thing gets up being 2 tons. A sheriff actually saw how fast I could get up and pulled me over yesterday after I took the fam out to breakfast. :driving:

No ticket though. :-)

I have a modded GT that I bought new in 08 and the past fall I purchased a bone stock GXP M6. They are both low mileage cars. The GXP (12,000 mile) cost me $36,000.00 and I'm having trouble selling the GT (8,000 miles) for $28,000.00 with $10,000 in mods. I only bought the GXP for the manual and limited production. The GT is cammed and will kill the GXP. The GXP feels tighter but on the street you would realy have to push it to notice the difference. Now to answer your question if you don't care about the manual and plan on driving the car the GT dollar for dollar is the best bang for your buck.

Hi there :)

Get the GXP.

Hey, what happened to the vette?

Hey, what happened to the vette?
He's going to say it started to feel too slow. :drink:

Hey, what happened to the vette?

Got bored with it so I sold it and got the 335i. Now thats gone to and I have an SUV.

So Jeff, did you buy a car yet?

Not yet. Hell I just had the chance to drive on for a short while before the dealer closed (Sat night). The experience mirrors most of the mag reviews (postive). But I didn't jump on it as the wife/kid/sales guy was in the car. The auto seems to shift sort of lazy though. But I had it in normal auto and not sport. That makes a diff right?

So far I like what they are about. The red lighted guages seem easy enough to read. (test drive was at night). Hard to tell if this was a good example/poor or ave. But it seemed to be well taken care of. It's bone stock.

I haven't settled with the insurance company for the G35 yet. Hell haven't even been in contact with them for the last week. I'm hoping for a decent payout so I don't have to lay out much cash. I'm doing no payments on this go around.

The auto seems to shift sort of lazy though. But I had it in normal auto and not sport. That makes a diff right? It is one of the most complained about aspects of the programming of the tranny. Sport mode is a little better but it needs to be reprogrammed with an aftermarket tuner. Manual mode needs work as well.

People come up w/ this question alot...for obvious reasons. For me the answer is VERY easy, it comes down to whether or not you need a manual transmission. Now, since I bought my car new at the end of 2008, the GXP's were just getting on the lots. I test drove a manual GXP, an A6 GXP, and an a GT w/ sport/premium packages. The brakes don't matter to me since you can upgrade that as part of your regular maintenance (I did - see sig) and TBH, unless you're tracking the car the GT brakes are just as good performance wise ON THE STREET. The big deal for me was I simply couldn't justify the extra $10,000 at the time for a manual tranny...the auto GXP didn't blow me away enough vs. the GT so I got over it saved the money and bought the GT.

Now, the delta between used GT and used manual GXP has shrunk some, but not by much, so you gotta ask yourself is it worth the extra cash for a manual tranny...and believe, it IS the manual tranny that makes or breaks the car IMO, there are NO big, 4 door, RWD, reliable, V8 big power sedans out there w/ 6 speed manuals....NONE. Let alone "american" ones.

But for A6 cars, dollar for dollar the GT is the better buy every day of the week and twice on Sundays. You can match stock GXP performance w/ intake/dyno tune if you have a strong GT, take off the cats and/or add HFC's and/or add headers and you'll be slightly quicker than a GXP.

All that being said, if it were a $5,000 difference for the manual tranny and brembo calipers when I bought new I would have paid it, but anything more is too much, and in the used car market it really comes down to preference.

Stock for Stock, A6 to A6, mileage/color/condition all being equal, I would never pay more than $3500 for the GXP over the GT auto...that's more than enough $$$ to surpass it and when you mod the GT it becomes more "YOUR" car anyhow.

Oh and lastly, you mod the GT w/ say intake/headers/tune/brakes - now you got a GT that is faster than the GXP AND GETS BETTER MILEAGE - considerably, so keep that in mind too if it matters.

The big difference (though it was never worth the $10K) is the lack of DoD/AFM on the GXP.

This alone is a big hassle....especially when switching cams.

I am very nervous about the AFM valvetrain as my 5 months of warranty slowly creep up.

Looking back, I'd make the same decision and buy a GT. But if the spread was $5K (like it should have been), I would have went with the GXP in a heartbeat.

When you think about it:

1) The cost to produce an automobile with a manual transmission is CONSIDERABLY less money then to produce one with an automatic.

2) Actual cost of manufacturing a L-76 should be MORE then the cost to manufacture a LS3 (special lifters, solenoids, oil lines, CPU/TCM programming)

3) So that leaves the FRONT Brembo brakes....

I wouldn't be too worried about the DOD hardware a) when/if it does go - well then you get a new cam/lifters = power mod = more HP and more fun and b) I have nearly 80,000 trouble free miles on my L76 and I got those 80,000 miles averaging 19mpg, not 15, which is what it would have been w/ an LS3 and a 3.73 rear or whatever is in the auto GXP

I hear ya....

But sort of incorrect.

If it goes under warrranty (powertrain) they (GM) will only replace the DoD cam with another DoD cam.

I have 28K and I'd say I average very close to 19 and I have DoD tuned out!

funny. I leased a 335i coupe and when lease was up went with new GXP. I say go with stock GXP and then mod as needed based on what you want

Tell that to the guys that have lost their whole motor because of a lifter failure. While there haven't been tons of guys losing their whole engine because of the failure, there have been a few on the forums. My recommendation is to do the swap before the failure. It's called preventative maintenance...

You can match stock GXP performance w/ intake/dyno tune if you have a strong GT, take off the cats and/or add HFC's and/or add headers and you'll be slightly quicker than a GXP.



Wow you can get an additional 55+ hp from a tune and CAI? :sneaky: Hmmm...

GT w/full exhaust/tune/intake, that gets you 400hp all day (at the motor), I see that setup being close to LS3, but I think its a stretch to think a tune/intake will get you to 415+ hp from the L76...if I'm wrong then that's a news to me, and definitely awesome for GT ppl!

Yeah there's always those few unfortunate 'guys on the forum' that have been dealt a crappy hand, any make or model ever made by any OEM, ever!

Replacing perfectly functioning lifters because 'a few guys on the forum' had issues is not preventative maintenance, it's insanity...and I don't see many dealerships jumping at the chance to replace normally functioning engine parts under warranty.

Just because an issue happens to a handful of forum members does NOT mean there is systemic failure waiting to happen to everyone else...ppl fall into this belief way too often IMO (for the right reasons, we all love our cars) but the reality is for every failure there are MANY thousands of vehicles that will function normally through useful life...paranoia will destroy ya ;)

GXP....
better gearing +500, shocks +350, rear sway-bar +50, brakes +500, forged 19" wheels +1500, rear lca outer joint +200, front fascia +500, rear diffuser +150, much better exhaust/mufflers +500, steering wheel +100, GXP on seat backs + 500, and has blue-tooth on all +200.

worse gas mileage. that is all.

If you add it all up the GXP is worth approx. +$5000 more than GT. Depends on if you agree with my values, which do NOT include instalation cost, and are subjective.

If you include the actual price of upgrades and install you well are over $7500.

I bought the white gxp in Austin for under 28 with 37k on it.

Oh and I have driven about 8 of the regular gt in search of what I wanted but they really don't do it for me. Sorry. It's just not the same as the gxp. And since everyone wants 25 k for a used gt and I bought my gxp for 27k I think it's more than worth the money. From what I have seen the forged wheels better motor and better brakes make the gxp worth the cash. Other than that they are about the same. But from looking on cost of parts u will see that the gt costs a good amount of cash to upgrade. And ur still limited to the stupid afm heads. Plus which will hold value better gxp one of like 1800 or gt one of 20k?

stick?

I went from a 2006 M3 to the GXP.

how does the gxp compare to the M3? which one do you like better?

Auto.

If you're thinking of keeping the car long-term and want the most resale later, the GXP is the better bet. The "GXP" aura has a surprisingly strong clout associated with it (even though a G8 GT could destroy a Bonneville GXP LOL), and because of that the "top of the heap" G8 GXP will always be a collector's item.

I was looking for a GXP when I was looking for my car, but the only ones I could find in Ontario were literally TWICE the price of a comparable GT - yes, about $50k. That's just plain gouging, so my choice was easy. At American prices, the GXP sounds like a great deal.

My car made 332whp on a mustang dyno w/ mods in sig. Do a search on what some stock A6 GXP's dyno...that's why I'm saying what I said. Depending on loss its 405-415 at the crank. There are some A6 GXP's putting down 340ish whp, some guys only putting down 320ish stock, and some as high as 350 even. But same day I put down 332whp w/ my mods an LS3 A6 vette dynoed 352whp, so thats 18.2% drivetrain loss, which would be VERY accurate huh? So given that measure, my car w/ my mods in sig was making 406hp @ the crank - very close to a stock A6 GXP - or in the ballpark right?

I guess we can agree to disagree, 406hp or 415hp ehh, I've seen G8 GT's w/ my same mods cut 12.999999's and 13.0 and 13.1 - and that is definitely same territory as A6 GXP. The rear end on the GXP is better but can also muck up your launch.

Anyhow the OP got an auto and that's his prerogative...for the price he paid I think he got a very good deal, at that price I DO think its worth a slight premium, but when they were new? LOL at somebody paying $10,000 more for an auto GXP!

Sry such a late response - hope you catch this

Well while you're making some assumptions/taking some small leaps of faith I can see why given your observations (FYI - I'm basing my logic from my LS2 GTO days...which I think you had too, right? Thought the name looked familiar from the GTO board)...

Anyway, I assume ;) the LS2 would respond better to those mods than the L76, and since the numbers are high for the LS2, they should be correspondingly lower for the L76, right? Dunno, but I guess it's possible(?)

Modded GT hands down. :driving: No comparison. The price difference alone makes the GT a better valued car. To get to the level of the GXP, a smart shopper will spend less and get exactly what they want on the car ie... suspension, cams, tunes, etc.. you get the picture. There is a reason aftermarket companies exist. Get what you want, make your vehicle better then the manufacturer. I'm jus saying. :wiggle: Unless you're a collector, why buy a GXP, it's not a car that will increase in value. A collector will drain it and leave it sitting to maintain it's value. I presume most of us that own these cars are working class folks, it would be fooled hearted to buy a car for an investment or resale value. You'll never get close to what u paid for it. I get GXP's are rare, only because the Chief went out of business, but they are not limited edition cars. There is a difference. I do love our small community we are truly a rarity! :attachment:

The OP ended up with a black 08 GT so he's happy. I agree that the GT is the better value as well.

Yup. I ended up with a 2008 GT with 40k. $19,500. That's well over $10,000 in mods to match the GXP specs. But I admit the GXP is one compelling machine and I'd love to have one.

But the budget I made for myself was to use the $ from my totalled G35, add less than $10 grand and buy the best GT I could. Or up the limit on the cash and try to squeeze in a GXP. But due to the fact that most if all GXPs were well over $30,000, I couldn't justify the expense.

When I made this thread, there was a GXP in Austin, TX for sale for $27,000. THAT would have been worth it to me. As the going price for GTs around me were $23-$25k.

I got lucky and found this one for $19,500.

Basically a miracle would have to have happened for me to get the GXP. One person that got the Austin GXP got one hell of a deal.

But the thread was very informative. Thanks!

That's my gxp. Bought it from roger Beasley. Same place I bought the mazdaspeed we owned

That's my gxp. Bought it from roger Beasley. Same place I bought the mazdaspeed we owned

Yeah, I sort of hate you for that. hahahaha :wink2:

I would have had to call and pay sight unseen to buy that.

You talk them down even $500?

Nope. They gave me first shot cause I bought 2 other cars from them. Price was not neg!

GXP for sure, I can only imagine how fun this car would be to drive with a manual tranny...

That's the ONLY reason I'd get one, but again - when I bought NEW I couldn't justify the $10,000 leap...believe me, I TRIED to justify it, but then when you factor in the abysmal gas mileage in comparison (lack of DOD + the 3.73) and me using the car for long freeway trips for work it just didn't make sense then, and surprisingly both models have held their values comparably, so it STILL doesn't make sense - unless you NEEEED the manual tranny.

I've learned to live w/o it - after a good tune these A6 cars are very responsive in manual mode.:driving:

I've said it before and I understand it is offensive to GXP owners in a way, but IMHO buying an auto GXP and paying that premium is just plain dumb. For 1/2 the price difference between the 2 cars, or in other words $4-5,000 you can have an A6 GT that will CRUSH an A6 GXP any day of the week and twice on Sundays. Just sayin....intake/tune/headers/cam and/or throw in brakes too if you want. You can do all of that for $5000 if you're smart about it.

I agree with most of that...except I get better mileage in my m6 gxp than I ever did in my gt.

Well I paid 27k for my auto gxp. And I didn't find a nice g8 gt for under 25k. Just saying. I think ur really looking at very different cars. I drove about 14 g8s. Gt gxp manual auto. Cloth leather u name it every combo. They are different cars. And by the time u piss with the dod and all the other crap a g8 gt didn't do anything for me. It's like saying the difference in cost between a v6 and v8 you could find a wrecked vette get the motor mod it and put it in the v6 car. Who really wants to do that. At the end of the day u will always have a g8 gt. everyone on this forum looks for and wants a gxp. It's like a 69 mustang. Yah u could get a 289 and make it faster but everyone wants a boss302 or 429.

If u spend enough money u can make a bathtub run the 1/4 mile in 7 seconds!

That's because you found a gxp for $6-7,000 below market! Awesome!

Not $10k different. $2k different absolutely. You got a great deal, as did I. But the point being made is gt's can be had for $21k going up to $27k. Most GXP's are going for $32k and up. For less than $6k, you can have better than gxp power, handling and braking.
