We had a problem with our engine and the injector needed to be replaced. This is a very trustworthy mechanic. They charged us a reasonable price and did the job in a day and recommended something else to repair in the future, but didn't need to do it now. Highly recommend working with them.

Welcome

Welcome to Automotive Authorities LLC

Training, Experience & Passion for Auto Repair

At Automotive Authorities, we’re passionate about cars, and that means repairing vehicles thoughtfully and respectfully. Some auto repair shops unnecessarily replace parts and entire systems instead of truly diagnosing and fixing the actual problem. Not here. Our mechanics take it to heart—and mind—that you can’t be an authority without knowledge and integrity.

If you’re looking for an auto repair shop you can trust in the Longmont area, please give Automotive Authorities a call! We are driven to do our job right every time, and are rewarded by the smiles we see on our customers’ faces. We’d love for you to become part of our extended family.
