Hi, I'm really interested in racing IT but I'm still rather overwhelmed with information since I've never raced before. I've come to the conclusion that I want a pre-built car and that I'll shoot for ITC, ITB or possibly ITA. I've looked at an MR2 but since I'm not the thinnest guy I'm worried about weight issues.

What I'd like to know is what are your top 5 car choices for each of these classes when it comes to competitiveness? What about cost and parts availability? Also, which cars would be best for a guy carrying a bit of extra weight already?

Thanks for any information!
