Should I trade my CTS-V for a Z28?

The market for modified late model cars is generally much smaller than it is for stock cars. Most dealers can't work on high HP modded cars and most of these builds are not emissions legal. Not all Performance shops use the same quality of parts and have technicians with the same skill set! The list goes on.......... I wouldn't expect most dealers to have much interest in a modified car.

So modding it to trade it in down the road might not be your best bet.

But if you want to experience 850hp of Cadillac fun, you are not likely to find it at your local dealership.
