Look at the Cars Available = a) find what models are available from b) what vendors and c) what are the price ranges. Naturally this applies to any allowed parts upgrades, esp. tires.
Run It First = we need you to be able to speak to your actual experience running and tuning the car. It would Also be great if you let a few other members try out the car(s).
