Mechanic

If you think your mechanic doesn’t have to deal with getting certified like other professionals, you are quite possibly mistaken. We say “quite possibly” because mechanics generally aren’t required by law to get certified in this country, so it’s conceivable that Bub down at the local filling station doesn’t have any meaningful credentials hanging on his wall. However, since the founding of the National Institute for Automotive Service Excellence (ASE) in 1972, a culture of professionalism has emerged and today about half of the country’s auto mechanics are ASE-certified. There are other kinds of certification, too, and other issues to consider when searching for the right mechanic. We’ll walk you through the details.
