I agree 100% its very easy to sell your addons for a decent amount and by leaving them on your car not only are you not getting anything for them but your dropping the value of your car as well. You will end up in a much better situation stripping down all of your addons and getting it back to stock as close as possible.

Good choice on the '08 vette they are sick rides

 

+1...99% of g35 buyers are not going to want the turbo, and all the mods that come along with it. Part out your car and get as much money for those as you can or plan on losing a lot of money because most people wont pay extra for aftermarket parts...gl with the sale! Unfortunately here in the bay area cars are going for 1000 to 2000 below KBB.

 

On a side note over here in NJ coupe's sell extremely well, I looked at a recent wholesale list and most are going for kbb sometimes more. These are the prices for dealerships which is great for us and if your on the east coast, but these are bone stock coupes.
