That guy doesn't give himself enough credit. That looks like a lot of fun and an ambitious project that most people would have never completed.
Years ago when Tony George started the IRL, I bought some parts from a sprint car fabricator in Indy. He told me that Tony George had bought up all the Indy Lights cars (3.8L Buick V6) because CART was not supporting the series. You could buy one with spares for $15-20K. Like a lot of things, I wish I would have bought one but part of me is glad I didn't.
