What People Are Saying

Don’t just take our word for it. Take a look at our verified Google Reviews.

I had them do a pre-purchase inspection on a 55 ft yacht. They were incredibly thorough, saved me 10's of thousands in unknown repairs. Best diesel mechanic in San Diego! Great office staff too! Cant recommend enough!

I am not the easiest customer nor do I normally write reviews but I felt compelled partly to help others pick out the right mechanic. These guys are honest, fast and great at what they do. I have nothing but great things to say and would recommend to anyone. Thank you Team Coleman.
