Without a doubt the best automotive maintenance shop in Longmont and most likely in all of Colorado! Totally honest (by far the most important quality of any repair shop) and extremely knowledgeable. Rates are at or below other repair shops. They go the extra mile to help keep your vehicle running smoothly so it's worth the extra mile or two to go to their shop; which is a few miles east of downtown Longmont on 119. Give them a try, you will be glad you did! Charlie Y. via Yelp
Had my Jeep Wrangler in for some work after receiving a ridiculously high estimate from a dealer. They were very busy, so it took a couple of days, but Tom kept me informed of progress and went the extra mile in asking about how I use the vehicle. They performed the work very well at a much more competitive price. I'll definitely be using them again as a local provider I can trust. Barry B. via Yelp
