What kind of warranty do you have on parts and labor?

Any reputable garage should provide a warranty on its labor; 60 to 90 days is typical, 30 days is the bare minimum. The parts should come with their own warranty from the manufacturer. EBC brake pads, for instance, come with a 12-month, 10,000-mile warranty. It's often a sign of good parts if they come with a longer warranty. If the shop you're visiting won't show you a warranty policy on both parts and labor in writing, that's a red flag. "Obviously, you don't want to take your car into a shop doesn't guarantee its work," Cox says.

Can I have my old parts back?

You are entitled to get back any parts that are replaced on your vehicle. "In the state of California, for instance, it's law," Cox says. The exception to the rule is with remanufactured parts. According to Cox, sometimes your original parts are surrendered as a "core" charge against a discounted rebuilt part. Essentially, you are buying the remanufactured part, then getting a refund for the cost of your core damaged part. What you pay is the difference between the two parts. This is typically the case for complex items such as pumps and transmissions. Regardless, you can still ask to see the part. Any shop that refuses to show you the part or hand it over could be hiding something.

Have you ever worked on this model of car or made this repair before?

Just as valuable as experience is relevant experience. Not only will those mechanics who have experience working on your model of car know what to look for, but they will also likely have the tools needed to work on your car. "See if there are vehicles similar to your car in the shop when you go in there," Cox says. There are also plenty of resources online to help find a shop that can repair your type of vehicle. Some shops specialize in particular brands and will advertise themselves as such.

Can I get a written estimate before you do any work?

This is nonnegotiable. Nobody should put a wrench to your car before giving you an estimate. And once the repair is under way, any work above and beyond that estimate should be cleared with you before it's done.

If you don't like the first estimate you get, feel free to shop around. "If a mechanics is confident and knows what he's doing, he should feel totally comfortable with that," Cox says. Just because a shop looks under your hood, you are under no obligation to give them your business.

Now tally the scores for each right or wrong answer to see where your mechanic or shop places on the scale below.

  • Any shop that scores between 12 and 17 points is a good bet.
  • Any shop that scores below 10 should probably be avoided.
  • Any shop that scores negative numbers shouldn't be in business.
