Automotive Repair

Best service at the best price

The new carwash is great - does a good job and the line moves so much faster than most any automatic carwash.

Very good service.

We had a blown RV tire on Memorial Day and Hester Diesel Services came out changed it for us and even repaired the old tire. He was reasonably priced, fast, and most importantly concerned about our safety. Thank you for being an honest business person.

I work for The Right Ride we buy lots of diesel trucks and get emission work done by them. Jesse is the guy to talk to!

Looking for a garage you can count on. L1 is the place. I have brought my cars here for years and feel confident my family is safe and secure on the road.

Absolutely amazing experience. Abe really went above and beyond, including giving me a ride to and picking me up from work when my car was ready. I didn’t feel pressured or taken advantage of, everything about this shop is fantastic. I’ll be back for any other repairs I need!

Purchased a truck with an engine built by elite diesel. Engine was 2 weeks and had a 2 year unlimited mileage warranty. There warranty service is horrible. Was lied to about the ETA on repairs. Followed by a large shop bill when it was finally completed. I recommend you do business elsewhere. The owner is impossible to reach. Avoid at all cost.

I highly recommend Rockin ‘S’ Diesel. I couldn’t be happier with the customer service, Rocky is a great guy and very helpful.

Outstanding service! After taking my truck to several other places Stan's Auto was finally able to help me figure out a misfire issue that i had been battling for over a year! Jarad in particular is great to work with and very helpful. I am grateful for the transparency and integrity of workmanship I received from this place, something which is hard to come by in an auto shop.

Twin Peaks Diesel did an injector swap on my 2003 Duramax that I've owned since new. They recommended Dynomite 50hp injectors and a Cat filter swap. Pricing was fair and I was impressed with their knowledge of the truck (it's a ZF6 manual and fairly rare) and didn't push anything, just their personal experience, knowledge, and facts. After extensive research I agreed to the injector upgrade and filter kit (which he installed at no extra charge since he already had it apart) and COULD NOT be happier. He said it would run better than new but honestly it's way smoother than new. The extra 50hp is absolutely noticeable, especially in the 2k-2800 rpm range. Can't verify mileage yet as this truck tows 90% of the time and I havn't towed but maybe a few short trips. I appreciate no BS shops that are fair on pricing, and so far cannot recommend these guys enough.

True professionals that do outstanding work. I'd hire them whenever I could. Best in Greeley.

The mechanics here are real professionals and I have found ASR to be honest, hardworking shop. Steve in the front office is a great guy— he always hears me out, explains things clearly, is able to be reasoned with, and has gotten me a fair price on all my repairs. Their honda guy even gave me advice to do some work on the car at home, which helped me get off some tricky bolts and replace the starter myself. I recently left Fort Collins to drive my 15 year-old Civic 1,000 miles to my new home of Chicago. I am going to miss having these guys around, but I know I can always call them with questions about my car. You Fort Collinsers are lucky to have such a good shop in town!

I recently had Tristan repair my truck. I was told I needed an engine that would cost close to 5,000. Tristan could have went with that but he proved my truck needed minor repairs and it ended up costing me 900 dollars. Completely satisfied with his honesty and thouroughness!

excellent, informed service. great customer sevice
