If you want to get the most out of your days racing, you should get a car in every class. For example, get a Civic DX for Class 8, an Acura RSX Type R for Class 7, a Celica SS II for Class 6, a Skyline GTR for Class 5, a 300GT for Class 4, a Corvette Z06 for Class 3, and a Viper for Class 2 or 1. Note: The faster the car and higher the class of the car, the more uncontrollable it is.
