I can’t say enough good things about Cliff! My daughter’s Mini Cooper developed a problem, and anyone who knows Minis knows they can be challenging to diagnose and work on. Cliff was able to quickly troubleshoot the issue, accurately diagnose the problem, and get it repaired much faster than I expected.

Cliff was the most helpful auto mechanic I've ever worked with. After getting a quote at another mechanic in San Marcos at $2700, I wanted a second opinion. Cliff picked up the phone at 8 pm and instantly was helpful. He worked to get me the absolute best prices for the part that was needed.

I was looking for a mechanic who could check my AC, no cool air. Cliff was able to quickly diagnose the issue and make repair. I felt he spent time to make sure he wasn't just slapping a band-aid repair on the problem. Communication was great. He'll be our go to in San Marcos.

Clif was great to work with. I broke down far from my house because my serpentine failed. He answered right away with very reasonable quotes compared to the shops in the area and came and fixed my truck within 35 minutes I was back running.

Son had vehicle issues and Cliff property went to his aide and resolved the issue in a timely manner and at a very fair price. Very reassuring for a Colorado parent with a student in Texas.
