I've never been to a NASCAR race. Not really interested in "cookie cutter" cars going 200 MPH in a circle.
I offer my apologies to anyone who takes issue with my comment. If you get something from it, I salute you.
Since the Camaro, Mustang and Challenger are all in production, I would like to see a revival of the Trans Am series. ("Trans Am" may actually be copyrighted/trademarked. I would be happy with a reasonable facsimile of the old series - whatever they want to call it.)
Cars should have stock body shells, floor pans, and engine blocks, and heads. Otherwise, give it hell. Run on road courses, of course.
