I agree with Stuart as a "used" car is just that. But a broken in car is a must when going to sell. Does "broken-in" constitute racing, auto-x, drag, etc I personally don't think so.
I think you have to consider the buying public on these types of cars. We have a small community here and for the most part people that want these cars don't know what and LS2 is let along ever been on a track/autox, etc. So when you build a more track oriented car these people aren't going to "get" it. I've listened to many people walk by a car and say, "I'd never own a car with a rollbar thingy".
