I have a totally stock appearing GSX that will eat a Viper. I look for cars with body kits. I don't care how nice they are, all cars with body kits are slow because the owners spent all of their money in the wrong places.

A show car is a lot more than a paint job. It takes more than a body kit and a paint job to impress. If you don't build your car for competition in car shows, then it's rice. Everyone with any american car or turbo car will laugh at you whether or not you think they mean harm. You will have no control of that whether or not you win trophies.

Do what you like, man. That's the #1 rule. Screw what we think (I'll still laugh at you if you get a body kit though).
