El Paso, Texas (NAPSI) - Finding an auto repair shop you can trust can be a challenge. Here are three warning signs to watch for on your next trip to the mechanic.

• While no one likes to be overcharged, beware of estimates that are well under market rate. This can be a sign the mechanic is using low-quality or even used parts. Some mechanics use lowball estimates to lure you in for additional repairs that they will tack on later.

• Automotive technology is rapidly evolving and some shops fail to keep up. Without up-to-date diagnostic tools, a mechanic could misdiagnose your problem, which means you’ll pay for unnecessary repairs that don’t even fix your original problem.

• If a mechanic employs scare tactics or treats you in a condescending way, move on. A reputable mechanic will take the time to explain your options just as a doctor guides you to make the right decision for your health.

Fortunately, there’s a free service called RepairPal that can help consumers find a trustworthy local mechanic. RepairPal independently certifies auto repair shops nationwide for superior training, quality tools, fair pricing standards and a minimum 12-month/12,000-mile warranty.

RepairPal also provides car owners with a tool that brings transparency to repair costs—the RepairPrice Estimator. Cited as a resource by Consumer Reports, AOL Autos and Cars.com, this patented calculator generates fair price quotes based on the user’s automobile, location, and the service requested. All mechanics in the RepairPal Certified shop network honor these estimates to give consumers peace of mind that they’ll never be overcharged.
