A basic warranty may cover almost all things on the car, and some people get what are called drive train warranties, which cover the various parts that run the car, such as the transmission, engine and the like. Another warranty that may be offered is the wear and tear warranty. Wear and tear can help cover things like wiper blades, or power windows and door looks, and even the function of power seats. Rust protection is an additional warranty that usually simply covers the car for a certain period of time from rust decay.
