The best auto repair warranty is usually sold from a company that is accredited by the BBB and also has better than a C+ rating and has been in business at least a year. There are very few auto warranty companies that fit this description. There are about 40 extended auto warranty companies on Google but only a handful that have a C+ of better. And of the handful only 2 or 3 have been in business over a year. You have to be careful about fly by nighters. There selling policies one day and out of business the next.
Also, look at the complaints history. In the Automobile Warranty industry there should be no ore than 30 complaints a year by an average size corporation. There are many that have a C+ but have only been in business 5 months and have 40 complaints. So weigh all these factors when choosing your policy.
Make sure that your purchasing it from an Auto Warranty Company that is a member of the VPA. The VPA is an association of Industry leaders that strive to regulate the industry with a code of ethics. Over 70% of the advertisers on Google are not members.
If you take all these factors into account , your Extended Vehicle Warranty should be there when the dealership hands you a huge repair bill. And if you do your research you can bank on that. Auto Warranties are a great service especially if your like most people and could not afford a repair bill out of pocket.
