What customers say
“My 2018 GMC Sierra 1500 5.3 had basically blown up on me. [He] did a complete diagnosis of the engine issues and at each step sent photos and called to explain exactly what the issues are and what the options to repair were needed.”
“Their quotes are accurate, and the work is impeccable. When the dealership wanted $1200 to fix an automatic lock, [he] found the real problem and had it repaired for $150.”
“[They] service all of our vehicles used for landscaping, personal use, and heavy snow removal. He is fair, perfectly honest …, the price is right for the quality of work, and they can do everything from the basics to custom exhaust and structural repairs. … You'll never go anywhere else!”
“I have a 2006 Ford F250 diesel truck and several other shops refused to work on it because it was a diesel. … Turned out that it was a $5 hose clamp and ended up being a relatively minor inexpensive repair. [He] could have easily charged me for parts and work that I thought I needed but only did what was necessary to fix the problem for the least expense possible.”
“One stop shop. … Super knowledgeable and one of the most honest people let alone mechanics you'll ever meet.”
“Very knowledgeable and courteous. He will take the time to explain without making you feel intimidated.”
