Drove it today... car is clean clean clean. However, the air filter bolts/nuts (2 of them) were missing. The complete air filter assembly seemed to have been placed back - perhaps it has a cold air intake in its place and was replaced with the stock assembly but not screwed to the mounts. Plus it was dirty but the rest of the engine was clean.

Also, the crank shaft pulley was wobbling a bit... not sure if normal but found posts about this being “normal” in the LS3 engine.

Their mechanics will be reviewing the list of things I found strange and will get back to me before closing the deal.

Not sure what else to check to figure out if after market stuff was installed then removed before selling.

Yup. Aftermarket intake was on there. Check the exhaust as well. Possible it had a tune. Would be good if you could get the old parts.

Check the paint on the bolts (doors/panels/pillars/hood) and see if it's scratched. If it is, then there might be unreported damage because the part itself was taken off... Check if the paint is smooth and consistent. A lot of people rely on Carfax for this kind of stuff but not everything gets reported. Check the underbody for rust as well as the subframe is made of some crappy steel...

Thanks for the pointers.... will check those when I test drive it over the weekend.

I have a pic of the engine and noticed a red wire that look as if going into the wiring harness of the headlight... any idea what that could be?

The red wire is most likely for HID kit(to power the ballasts).
