What my thoughts say about precision tune coupons
Convenience is the third reason. The warranties that independent mechanics offer on their car repair are generally good only at their own shop. If you're caught away from home, what good is a warranty for a shop a hundred miles away? National chains, on the other hand, have branches across the country, so you're almost guaranteed to be within a short drive or tow of a mechanic's shop where your warranty is good. That can mean considerable savings for you. You can also get personalized service at a chain just as easily as at an independent mechanic's.
