Anyone have any problems trading in there car to a dealer ship with minors mods on there car? Did they try to drop you down on the price due to the mods or anything?

 

Just take them off and sell them privately. You'll come out ahead that way.

 

^+1, no doubt. The dealership will give you less, and you'll also miss out on the cash you could have made by selling the parts. This goes double if you are dealing with Carmax - they're a good company, but they gave me less for my WRX because I had a freakin' K&N drop in and some 17" Rotas!
