Longmont Auto Repair

Great shop! I'll be back! Thanks Liz, Corey and everyone else!!

These guys were so nice and helpful. I always fear going to a mechanic because I know so little about cars. They helped me without charging me a ton and explained everything that was going on so someone like me could still understand. They told me what needed to be done right away and what could wait

Meets my expectations. Great price range

Very friendly and nice, always recommend. I asked for my car to be given a check up before a road trip and was charged nothing when my car ended up being A-OK. :)

The guys over here are awesome. So helpful and honestly just want to get you whatever you need and get you back in your car. Your search is over, BRING YOUR CAR TO AUTOMOTIVE AUTHORITIES.

Reasonable rates, great service! They are getting popular, so plan accordingly.🖒🖒

There is no other rating than 5?! I'd give 12 if possible... I brought a couple of cars in with extreme challenges. They cured them better than I would've ever imagined. Liz is at the front desk, she knows cars. She is awesome. Cody and the boys know exactly what to do. Not sure what else to say but you'll feel satisfaction in a job well done...

I have been taking my vehicles to Cory Olsen (Automotive Authorities) for 10+ years and he does the best work I've ever seen. He is honest and a perfectionist. I will continue to do business with him and his shop. Thanks for the years of great work.

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.

These folks are amazing. They did heavy transmission work, A/C work and a serp belt on my Murano. That's a lot to ask of an independent shop. They have factory trained techs, that really give a hoot about their jobs. My Murano sings after they worked on her! They fixed all the many little incidental repairs that come with heavy engine/ transmission work. I'm very happy. Great shop. Thank you!
