We all want to repair our own cars, but if we need to take it to the repair shop for a professional job, we need to be prepared. Most shops are honest and are there to help you save money by keeping your car in top shape. But just in case, here are 5 things you should be thinking about when you walk through the door of a repair shop.

        Beware the up sell. Automotive up sells are tough. On one hand we don't want to pay for work that our car doesn't need. On the other hand, preventive maintenance is the best insurance against future repairs. Don't be pressured into an up sell on the spot. Tell your mechanic you may want to do that, but to give you a couple of hours to decide. Do some research and decide for yourself when things are quiet and the pressure’s off.

        Find a mechanic who is ASE certified. ASE stands for Automotive Service Excellence, and they take their certification seriously. If your mechanic opted to skip the ASE, this might reflect on their dedication to keeping you happy as a customer. There are lots of good mechanics out there who aren't certified by ASE, but why take the chance?

       Take a good look at the shop's work areas. A good mechanic will refuse to work in a pig sty. They will keep a clean organized work area, and clean their tools and equipment on a regular basis, usually daily. The floor will be swept and free of old parts, peanut shells and soda cans. Don't worry about what the mechanic looks like, car repair is not a beauty contest.

      Second opinions are great, but be sure to make it an anonymous trip. It's fine to tell the second mechanic that you're there for a second opinion, but don't share the diagnosis or the cost estimate. That's sure to muddy the waters.

         Follow personal recommendations, not coupons or flashy advertising. This applies to mechanics, dentists and real estate agents. There is no substitute for a thumbs-up from a good friend of family member. Good shops know this, and their customer service reflects it. Remember, always stay on top of the situation and you won't be taken advantage. The more you know about your car and how it works, the more empowered you'll be at the repair shop.
