I had an issue that another shop in Longmont caused and left me hanging with. Stonum had the communication, patience and expertise to help me and fix it. Take it from an old gear head and ex power sports mechanic, Stonum is goooood. Patronize a home town business.

They always take great care of our cars, communicate transparently and effectively, track issues when they're developing but not yet problems and pace out repairs accordingly, and they charge fair rates for the quality of service they provide. The one time we had an issue occur after repair, they honored their warranty and fixed it for free the very same day we reported it so that the car issue wouldn't disrupt our family plans.Services: Carburetor cleaning

Always Mark, Kaleb and yes Peter were warm friendly and funny. My tech Sean did a great job, and no evidence left behind inside or out that my Stella had so much messy work done on her.Since I've found Stonum I've felt so at ease about any light or heavy service to be done on my '97 4Runner.Thanks Folks, please don't ever leave Longmont;-)~☆☆☆☆☆~

My van is running nicely! More smooth! All the checks done during a routine oil change are thorough. I like how the mechanic goes over things he noticed. I value and trust their opinions and professional advice on what needs to be fixed soon and what can wait! I would recommend them!Services: General repairs & maintenance

Friendly, professional, they keep you informed of what's going on. Or comes in on budget. They give me great confidence. I had extensive work done to steering and suspension, transmission maintenance, full brake job including new master cylinder. They do the job right the first time. It takes a little longer to do it right the first time.Services: Transmission

I have been taking my car here for years. I love how they take pictures of the repairs. They have a nice online portal where you can go to see the repair history of your car.Their pricing is fair, I have gone to cheaper places and lost use of my car for several days because they made a mistake during service.They have a ride service that can take you home or to work after dropping off your car and can pick you up when it is done.I never feel cheated. They are very frank on routine maintenance and when things like brakes should be replaced. They have been measuring my pads and reporting it the last couple of oil changes because they are close to needing replacement. It is nice getting honest feedback on what the manufacturer recommended services are at certain mileages and asking me if I want to do it.I 100% recommend Stonum for any car repairs you need.

My daughter took her car in for new spark plugs after Napa recommended them. The mechanic broke 1 off inside the engine and they wanted to charge us $2,500.00 to fix the issue they caused. My daughter's car drove in there but had to be towed away. The manager Mark Shy just continued repeating "Its not our fault", every other business I talked with about this stated that as a "reputable" business you fix it then let the customer know what happened. We asked they start an insurance claim, my daughter heard from a woman 1time by phone then said a separate adjuster would be out for independent review. She got an email stating it was not their fault and after several attempts to contact her never heard back. We are not even sure she was really an insurance person at this point. We picked up the car and NOBODY came out to say anything!!!!!! Stand behind your work with honesty and integrity not charge a college student what your mechanic broke!!!! Several mechanics we talked to said there had to be significant force to snap the plug off like that and in their opinion, it is on the mechanic to fix. I will NEVER recommend this company ever as their customer service is the absolute worst and all they care about is creating more business by breaking vehicles. Now my daughter is stuck with a non-running vehicle, is in college and working. There is something really wrong with a company that won't even try to work with a financially strapped person when they are responsible for the vehicle in their care. You broke it so you should fix it!Service: Auto maintenance
