Great local diesel shop. Christian is very helpful and professional. Was very clear on the issues I had and provided quick turnaround and fair prices.

Best diesel mechanic I have found in Denver. Honest, fair, quick, expert mechanic. Christian, his dad, and the rest of the team are among the best in the area—unfortunately my truck has been around the shops in Denver, ironically not much since I’ve been to Marcelo’s though. Support this business and thank me later.

Every mechanic I went to including the dealer could not figure out my problem,Marcelos took the time to figure it out,and this is a is a first they did not charge me to to find my problem and fixed it,thats the way it should be treat people right do good work and they will beat the door down for your service.

I didnt have any work done here but I popped in to ask some questions and they were super helpful, I would definitely use them if in the area.

They did a thorough job of fixing my truck. And communicated with me anytime there was updates.

They take forever to fix my truck
