Longmont Auto Repair

Automotive Authorities were willing to work on my 1972 Ford F100 (which is hard to find a garage that will), and did a fantastic job. They fixed a screwup from another vendor that had rebuilt the engine and also brought to my attention some potential issues with my brakes that had the potential to be deadly if ignored. Truly grateful for their in-depth examination of my vehicle.

AA did a great job of fixing my top end after the dreaded AFM failure. Thx GMC for such a flawed system that breaks on almost all these series of trucks. All new lifters and push rods. Expensive fix, but well done. After the job, the o-rings on the injector(s) were leaking causing a pfft sound. Paid to have that fixed with new orings on all eight existing injectors, but after that, one of the injectors was running really rich and caused a permanent check engine light. Cory agreed to cover all the labor to swap out all 8 injectors whereas I covered the cost of brand new GM OEM injectors. A fair deal I felt. Runs great so far. Dutch is a great mechanic. Thanks Cory, Andy, and Dutch!

Always a great experience. Professional, knowledgeable, and safety minded. I’m a fan!

Always a great experience. Professional, knowledgeable, and safety minded. It makes such a difference to work with a local small business instead of a factory dictated dealership! Im a fan.

Everybody there is great.They made sure I had a full understanding of what the problem was, and what needed to be done. Great pricing,and just super nice guys. I will definitely be back for any work that needs to be done on my cars in the future.

These guys were super knowledgeable, and very pleasant to work with! I highly recommend!!

Saved the day on the Friday after New Years! Friendly and helpful, went out of their way for me.

Friendly and helpful, saved the day on a Friday when others would tell me to book an appointment weeks later.

I met one of the mechanics in an AutoZone parking lot, when I wasusing the diagnostic tool to check why my engine light was blinking right after having my catalytic converter replaced by my previous mechanic. The mechanic from this shop was able to offer to read the diagnostic tool and explain the problem to me. I asked him for his card and, scheduled an appointmentand they repaired my engine and importantly, gave me a good price and really made sure that I understood what was happening with my truck. Im very pleased to have found my new mechanic!
