5I had a deadline to get work done. Gary and team stepped up and helped in a big way. I highly recommend them 👍
Bought a boat that needed some love. Some of the issues we were able to work out ourselves but in the interest of saving the marriage we brought in Coleman to tackle the jobs that were either too big, too hard or just too much of a pain.
Similar complaint as the others, Jerry, the owner, is very rude and in general, not somebody I would give my business to. Go elsewhere. Many other superior options around town anyway.
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!
Never did I think spending $30,000 on a new motor would be so difficult. Greta found a way to do that though! Refuse to work with the customers request, put her own personal interpretations and feelings into my project as a customer.
