There are two main kinds of extended auto warranties. There are auto warranties that are bought through aftermarket auto warranty companies and there are auto warranties that are backed by a manufacturer.
An extended auto warranty that is bought through an aftermarket auto warranty company tends to be less expensive. Also, this kind of auto warranty tends to vary in both price and quality depending upon which company you buy from. This is why it is always important to do your research before making a purchase.
An extended auto warranty that is backed by the manufacturer generally includes a wide variety of repairs and services. Repairs performed on your vehicle are usually done in a dealership that is approved by the manufacturer. This means that you will not usually experience any issues when going to get them done.
No matter where you get your extended auto warranty company from, it is essential that you do research. Compare a variety of warranties for price and quality.
