The best way to save money on cars is to keep yours as long as possible, and the best way to do that is to have it serviced well and regularly. To find a good mechanic, try calling some classified ads placed by people selling cars similar to yours. They might have a good suggestion. In most cities, you can also check with AAA, even if you’re not a member. At the minimum, find a mechanic that’s certified and experienced with your type of car. Always get estimates in writing before work is done and always get used parts back.
