Here's my idea- basically, you are restricted to any car in the game in the dealership that has 400 PP or below. Any one of them. However, they must be buyable below 50,000 credits or some low number like that. I can't stop people from making modifications to the cars (Because if not somebody will find the best 400 PP car under 50,000 and next thing I know it's the Honda something series), but the only restriction beyond that is a universal tire compound. Anybody interested in this?
