2 things go against the theory that cars lose less value...
1. Drive it off the lot, turn around and go back and ask what they will give you for it
2. Drive it off the lot, run it into a tree and see what insurance will give you.
In both cases, the max amount you will get is 80%. that's been the rule. No idea why people would think differently. I'm not saying that low mileage newer cars have not garnered rediculous prices...factors which may be in play involve different credit ratings for used vs. new, cars no longer available, or limited run (basically a supply/demand issue). I remember back in 1987 I was trying to buy a new camaro. They would only sell me a used one (for the price of a new one) because of my credit.
The Economy is another big factor. If new cars are not selling, the price for used ones goes up. Once the new car market heats up, used prices should come down as supplies increase.
Also, a quick autotrader search finds a good supply of Camaro SS at the same mileage, and a year newer for the same or less money.
I guess I have heard stories about folks who have gotten a great deal off the showroom floor, kept it a year, and sold it for a profit...just never happened to me.
You can choose to be anything you want on the internet...why choose to be so stupid!
