The RS3 is the first car in the C-Class that you can get for credits. Its a well-balanced car, but its nitro duration is not too good. For 18,000 credits, you can get this unrealistic (really) Audi that isn't really worth raving about. If you are starting out, then this car is perfect for you.
When you MAX this car, it is still pretty bad.
