Longmont Auto Repair

Brought my truck in with an electrical problem. They diagnosed it, got the part and fixed it same day. Awesome service, and very friendly service writer! Highly recommend these guys!

Just want to say they are the best! I took my truck there to get some work fixed that another autoshop messed up...When I took the truck it was a mess ( parts missing, broken pieces, timing belt put on wrong, O2 sensors put on backwards, and more) Automotive Authorities figured it all out and got my truck running within a few days. They were professional, and super friendly!!! Will definitely go back.

This place saved me today. My car broke down this morning and they did everything they could to get it done for me today. I called about a million times and each time they were so nice and understanding. They were very helpful and answered all the questions that I had. Awesome job guys!!! I would definately recommend this place. Thank you so much for all you did for me!

They didn't try to upsell me on anything I didn't need and I will absolutely be back. Fantastic service.

Great place to get work done.

The team at Automotive Authority really live up to their name. They know their stuff and it's clear they care about their customers.

When it comes to a Duramax diesel, Cory is the man for the job. Extremely knowledgeable and easy going

My partner and I live in a school bus converted to RV, which, when we recently in Longmont, was having a number of issues. After another shop in town not only failed to fix the issue but also backed our bus into something and thus annihilated my bike hanging on the rear, we decided to give Automotive Authorities a go. Through a tumultuous shitstorm of diagnosing and repairing, reevaluating and persevering, Ti was both professional, meticulous, and a pleasure to converse with. In addition to the awesome service, the whole crew was super accommodating of our predicament as two folks living out of a dysfunctional vehicle, and went above and beyond in helping us out. Highly recommend this mechanic to anyone in the area!

Cory and his team are amazing! They always explain everything that needs to be done. They work me in on busy days and complete jobs in the estimated time!

Great service and respectful staff! Highly recommend this business, Cory is very professional and happy to work with him!
