Earlier this week my clutch blew up in the middle of I25 on the way to Fort Collins. I was able to limp off the highway but soon found myself stranded. I had the tow truck take me to the nearest garage, which happened to be Carbon Valley, it was around 11am. I was now looking at being stuck 60 miles from home for an extended time. The team at Carbon jumped into action immediately with smiles on their faces. They hunted down the parts needed, disassembled the broken clutch and replaced it by the end of the same day. They even stayed after closing so I could race back there to pick up my car, which now works better than it has in years. I couldn't be more happy with their service. They turned what could have been a disasterous week into an inconvenient afternoon. They've gained a loyal customer in me. Can't thank them enough!

Carbon Valley Garage did a fantastic job on my truck. Truck actually sounds quieter after the transmission flush. Cost reasonable, actually less than dealership quote. Warm greeting at door, offered a ride home but not needed, quick service and back on the road again! recommend this garage for ALL repairs. Knowledgeable staff and the follow-on email with diagnostic pictures and descriptions are invaluable.

I highly recommend Carbon Valley Garage. I had reached out with some questions regarding cost and repairs. I scheduled a drop off time but ended up dropping off the evening before for convenience. The work was started that evening and completed before the original drop off time ever happened. I was kept in the loop through text every step of the way. As someone who doesn’t credit herself regarding knowledge of cars and repairs, it was refreshing to speak with people who were honest and fair about the repairs and cost.

Top-Notch Service and Communication Excellent service from start to finish. What really impressed me was how transparent they are—they send you videos and pictures showing exactly what’s going on with your car. If there’s a problem, they’ll walk you through it in a video, explaining what’s wrong and how they plan to fix it. They do a full check—tires, oil, everything. If they find something that needs attention, they show you the evidence and leave the decision up to you. There’s no pressure at all, which I really appreciate. They worked on my ’03 Silverado, and I was amazed—there wasn’t a single scratch or even a fingerprint around the hood or engine area. I don’t know how they pulled that off, but it shows how careful and respectful they are with your vehicle. Most places leave marks, but not these guys. It’s clear they care about your car and your business, treating your vehicle like it’s their own. Communication was great throughout the whole process. Highly recommended!

This shop is very professional. They discovered issues that another shop claimed to have fixed, but those issues were never resolved. They did complete an oil pan gasket, and so far, there have been no leaks.

They ran a diagnostic and moved sensors as to not charge me for new sensors and to see what the real problem was. I also got an oil change. It was a great experience.

I bought this truck used and have been chasing a front end shimmy issue for over a year. I’ve had three garages work on it and the problem was never resolved completely. I was able to track down Mike and found out this shop was closer to me than I thought, so I dropped it off. He took care of all of my issues and finally! My truck feels like it should. It means a lot to me to have a shop that I know and trust. Thank you William and Mike for your great service. This will be my go to garage!

Went in for a diagnostic/estimate and they were able to fix the problem for minimal cost. They were thorough and provided an update that showed all the work before I picked up. I was lucky to have same day turn around!

We have been using Carbon Valley Garage for years for routine maintenanceand repairs. Owner Chris always take time to explain options for repairs, when needed. They typically provide quick turn around times and we have always been satisfied with their work.

My radiator busted on I-25 and I had to make an emergency stop at the first exit I could find. Carbon Valley Garage was the nearest shop I could tow my car to, and I believe fate was on my side with that. They were kind and compassionate over the phone, which was helpful given the state I was in. They got me in immediately and gave me a loaner car so I could make the 45 minute drive back home and be able to go to work, etc. for the next few days. My car had just hit 200k so I had them do a full “check-up”, and my car is running better than ever now! The whole time they were courteous, communicative, professional and trustworthy. I have dealt with them a few times since then and they always give a five star service. Would highly recommend them to anyone.

CVG are good local people, I have trusted them for about 3 years with all kinds of work on 3 vehicles. Certainly more personalized, reasonable and thorough than the dealerships. Definitely recommended.

Brought my wife’s car in with a check engine light on. They ran a full vehicle diagnostic (spark plugs) and sent me the results later that same day. Their online system was super user-friendly, I was able to customize the approval for what work I wanted done and not done. They had the vehicle repaired by midday the following day, great staff and easy to talk to! Will be coming back and recommending to friends/family!

The team at Carbon Valley Garage was so thorough, knowledgeable, quick, and kind. I felt informed every step of the way!! I love how they document the work/repairs needed on your vehicle with photos and videos and then include that electronically with a quote breakdown. It was very efficient. I really appreciated how the team worked with me use a loaner car while they made repairs, it was an unexpected benefit that made a difference in determining when I could leave my car with them for the repair work.

Honest, and reliable, great service, they stand behind their work. It took me 12 years to find a honest, experienced mechanic I can rely on every time . I am a real person, not friend-family or paid for my comments. If you want a honest, reliable mechanic work done you found the right shop. If your looking for the cheapest fix, and like paying for it twice because it wasn’t done right go somewhere else.

Took truck in for alignment and diff fluid and xfer case fluid changes. Folks here were very informative and easy to work with and talk to. Prices were reasonable and service was great. Took time to explain what they found, including pictures and notion to keep an eye on certain things. Overall great experience and wouldn’t hesitate to use carbon valley in the future.
