Best car for each SERIES

I’ve done a lot of searching but havnt found any answers. I’m looking to know what cars are the best for each series - such as Sport Compact: Early Sport. Or modern sport. Or production rally.
Right now I’m on Specialized/Track Toys and will be moving onto Ultimate Track Toys…etc…so please list your favorite car (not by class but by series/championship series or whatever) and tell me why I should chose it.
Thanks :slight_smile:
Sorry if this is a repeat post - I’m drunk.
