"I own a boat on Lake Lanier that has 2 large Cummins diesel engines. For 6 months I contacted every diesel mechanic around the lake and I could not find a single person that was willing or had the knowledge to resolve the problem I had with one of the engines. I decided to take a chance and look for someone in the Athens area and I found David. David came up to the boat the next day to assess the problem. Two days later he came with help and within 3 hours, the problem was resolved. David was both extremely knowledgeable and very professional. I would highly recommend them to assist others in need..."

I called Oconee before business hours and got no answer. 15 minutes later I got a call back and they drove out to me within 30 minutes to help me. I needed a new water pump, serpentine belt and coolant. They brought the parts and fixed right on the spot. They gave me a rough estimate ,which was not far off from the invoice. They even honor military discounts. Their prices were far better than anyone else in the area. I highly recommend this company..."
