Best heavy-duty mechanic in western Colorado Rich is honest and quick to get you back on the road and super affordable prices

Rich was able to diagnose and fix my issue quickly; I was up and running in no time. I likely would have been overcharged elsewhere. Definitely recommend and will certainly do business with him again if needed!

They gave Great advice very nice person.

Great service! Very responsive to messages and appointments. Diagnosed the steering issue and explained the symptoms and causes my car had. Saves time and hassle that they come to your home or work place. Honest, professional, and curtious people. Prices were very reasonable and explained in detail. Better than dealerships. Definitely would use them again.

I am located in another state and am considering the purchase of a collectible 1987 vehicle. I called Rich and had him check it out. He was very thourough and inspected everything i needed to get an idea of the vehicles condition. Very prompt and professional on the phone, and he also took the time to send me lots of pics and videos. Top notch mechanic!

This is the mechanic I use to service my car... hes very good at what he does...

Very effective and efficient. I wish Id started with them.

Rich goes Above and beyond servicing our Fleet to keep us on the road, thank you, from Unifirst

Richard replaced the timing belt on my Ram 3500. He was friendly, professional and gave me tips on how to replace the belt, if I had to do it myself. I’m very satisfied with his work!

I am so thankful for Richard to have come 2 my house and fix my jeep wrangler. I recommended him any day of the week. Reliable,honest. And great low prices. 5 stars all the way

Rich Willis came to my house to work on a car that wouldnt start. His service was fast, friendly and very professional. His rates are fair and he provided useful suggestions regarding future maintenance. I highly recommend this service.

I was stranded on the side of I70 with a weird electrical problem. The owner of Driven Diagnostics was able to come right out. He plugged in some sort of flux capacitor to the computer port and was able to get me running. He was very professional and knowledgeable. Also helped me fix another problem I was having. Highly recommend.

Rich with Driven Diagnostics was awesome. He came right after I called him and fixed my daughters car. He was fair and honest. I would highly recommend him for your automotive needs.

Rich is great. I had power steering fail on an F-250 with larger tires and he came out and fixed the problem very fast and at a price that was very fair.I trust his work and that he is an honest guy.

Rich is the man he was fast professional and gave me the warm fuzzy feeling he knew what he was doing working in my Duramax I don’t trust many people to touch my vehicles but I was out of town in a bind and way behind and Mr. Rich helped me out and totally affordable, I will definitely be calling him again if I need repairs in and around Grand Junction.

Very cool. came out to us when we were stuck on the side of the road.is becoming our number 1 guy to go to.

Rich was fast and efficient with fixing my broke down rental RV and getting me back on my vacation
