Customer Reviews
"I had an excellent experience at Southwest Auto. It’s been very hard to find a mechanic to work on my old Saab, so I found Jon. He did a thorough diagnostic, emailed me the results, and had me approve the work. It took some time to source parts, but Jon Came through. My car not only made the 200+ mile ride home, it’s running great. Very thankful his shop was recommended."
David Dalrymple
"I highly recommend Southwest auto for your vehicle repair. Recently, they handled my transmission leak on a 3500 Mercedes Diesel Sprinter Van/Camper. They were efficient, fairly priced, and Cory at the front desk was very communicative during the repair process. They handled the warrantee coverage for me and got me back on the road quickly. I cannot say enough how pleased I was with the service they provided."
