I have looked closely at those that have been made "show ready" and instead of trailer, have been driven for a few years. You look at the engine, frame, etc. it's all rusted and pitted from road wear. It would make me sick to have spent that much $$ to make it a perfect representation and then to look under the hood and see a clot of mud stuck inside the coil spring.
IMHO if you're going to drive it don't doll it up too much.
