Brought my truck to jay, he did a wonderful job. Repaired my broken Y bridge, and went above & beyond to make the truck running perfect. I trust jay with any problems that may happen with my truck, he does it all! Best mechanic around here.

Great business, jay fixed my truck perfectly. he did everything I asked for, and didn't forget one thing. He went above and beyond to fix the problem, not just changing parts, but solving the problem that started it. I would recommend these guys for anything, and to fix anything, they are pros!

Jay and his staff rebuilt a motor for me on a 2013 GMC 4x4 truck. They did a super job, and I am so appreciative! Jay is a great guy, a true pleasure to work with, and I look forward to working with him again.
