If the car dealership you’ve been using for service has closed, Consumer Reports suggests opting for an independent shop.

If the car dealership you’ve been using for service has closed, it’s time to find a new mechanic. And unless you plan on driving a good way to the next nearest dealership, the editors of Consumer Reports suggest opting for an independent shop.

Your car will probably still be in good hands. According to a survey CR conducted last year of owners of almost 350,000 vehicles, people who used independent mechanics were generally more satisfied than those who had their car serviced at a dealership.

If your car is under warranty, you will still need to go to a dealership for warranty repairs, but you won’t need to go to the dealership for routine maintenance. Under federal law you have the right to have repairs performed anywhere you like without voiding the warranty.

But identifying a mechanic you can trust for your car takes a lot more than letting your fingers do the walking. CR recommends doing a little old-fashioned sleuthing. There’s no single clue to what makes a good repair shop, but here are some things you should look for:

Find a shop for your brand of car. Many garages specialize in certain makes. Those that focus on your type are more likely to have the latest training and equipment to fix your vehicle.

Ask your family and friends. Especially seek recommendations from those who have a vehicle similar to yours.

Search the Internet. Look for information about local mechanics on Angie’s List (www.angieslist.com), RepairPal (www.repairpal.com) and the Mechanics Files at Cartalk.com. RepairPal and Cartalk.com provide those services free; Angie’s List requires a subscription.

Check for certification. Your mechanic and shop should be certified by the National Institute for Automotive Service Excellence, or ASE.

Check the Better Business Bureau. Auto repair shops rank 12th on the bureau’s list of common complaints. Go to www.bbb.org; the information you find might help you figure out which shops you should avoid.

Give the shop a tryout. Before your car needs a big repair, you might want to try out some local shops with smaller repairs or maintenance items, such as oil and filter changes.

Ask about warranties. What kind of guarantees does the shop give on repair work? Warranties can vary greatly among shops, so ask about them ahead of time. Use a common repair, such as brake work, as your guide.

Make sure the shop is convenient. Even the best shop might not be worth the effort if its hours conflict with your schedule or you have few transportation options after you drop off the car.

Early fixes save cash

Don’t wait until the repair becomes a horror story. CR offers ways to keep your car in top condition.

• Check the maintenance schedule in your owner’s manual to see what service is recommended and how often. Follow it scrupulously for as long as you own the car.

• Mark your calendar with estimated dates for services such as oil changes, tire rotations and fluid flushes.

• New noises are not normal. If you hear something odd when accelerating, braking or turning, have it checked by a mechanic.

• At least once a month, check the levels of the car’s fluids, such as oil, coolant and brake fluid. The owner’s manual usually has instructions that are quite specific and easy to follow.

• At least once a month, check the air pressure in each tire, including the spare, when they’re cold. If necessary, adjust the pressure to match the carmaker’s recommendation.

• If your mechanic recommends additional maintenance services not specified in the owner’s manual, ask why they’re necessary. If you’re skeptical, check with other mechanics for additional opinions and cost estimates.
