According to the law every car should have an auto warranty either it be a brand new car or a used car. An auto warranty is a guarantee given by the dealer or the car manufacturer to the customer assuring him that his car is in best condition and whatever damages that the car may incur during a certain period of time would be repaired at free of cost. An auto warranty is like an investment that a customer invests on his vehicle 
An auto warranty comes with a validity period, coverage and with a price tag, the validity of the warranty may differ from car to car and depends on the warranty that you choose to for your vehicle. The coverage is almost an important thing and you should be completely aware of the things which are covered in the warranty. Mostly the things that are covered in the warranty are the engine parts, the chassis, braking system, steering system and many other things. Most of the things mentioned above are mandatory that means they are covered in almost all the warranties. Other wear and tear parts of the body are also given warranties but this depends on the company.
