What Cars To Use

I have came up with a list of some good yet farley cheap cars that will help a lot with certin kinds of races.

Race              Car
Street Cross     My favorite Mx-5 (good handling)
Drift Attack     Any car with good handlng.
Nitrous Run      Mx-5 (NEED GOOD HANDLING)
Drag             Charger (fast and good accel)

Circuit          Mazda Rx-8 (fast and ok handling)
Lap Knockout     Mazda Rx-8

Remember these are not the best cars. There are more expensive and better cars.
