What Our Customers Are Saying

“Gregg’s Diesel helped us out in a pinch. We were on a month-long trip up the coast, heading to Canada when our boat broke down. We were so relieved when we spoke with Wayne and he had a suspicion of what the problem could be right off the bat. Kurt came to our boat the following day and couldn’t have been nicer. That guy knows his stuff. Diagnosis was exactly what Wayne said, and Kurt found a couple other things that needed minor repairs. They got it fixed, made it easy and we got on our way. With boats especially, you worry that you’re getting taken advantage of, especially when you’re just a tourist passing through. I can assure you, they don’t gouge you on pricing and don’t sell you a bunch of stuff you don’t need. I wish we lived in this beautiful town and could make them our John Deere repair specialists full-time!”
