Visit the track(s) you want to race at. Find the most popular car there and get one of those. You'll be able to get setup help and maybe parts support. There are plenty of threads for all of the TC brands/models. Or pick a budget, and go from there.
Otherwise, you'll get a bunch of people that don't even run where you will telling you to get what car they run.
