Coffs Harbour diesel was a great help, my car broke down and Jake and his team were strait onto it getting it back on the road his communication and knowledge of the vehicle was amazing and just overall outstanding work to him and his team. Very good price on all his labour I’m very appreciative of the efforts they went through to get me back on the road.

I got towed on a Sunday here by nrma and came in Monday morning pretty depressed as you’d expect being broken down on the highway miles away from my destination. Scott and the guys got me back on track as quickly as they could. And the car is running great. They fixed what two other mechanics in Sydney had said they’d fixed but it obviously didn’t. So glad to find a shop competent enough to handle full injector replacement and all that entails. Not a problem for the guys at Coffs Harbour Diesel. Cheers.

Trustindex verifies that the original source of the review is Google. I had a fantastic experience with Coffs Harbour diesel. They were professional, honest, and incredibly knowledgeable. They quickly diagnosed the issue with my car, explained everything clearly, and gave me a fair quote upfront—no surprises. The work was completed on time, and my car runs better than ever. It’s hard to find a mechanic you can truly trust, but I wouldn’t hesitate to come back here or recommend them to friends and family. Great service all around!
