What customers say
“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.”
“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.”
“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.”
