Dalton Diagnostic Auto Center

David is a great guy and knows what he’s doing, always fixed the problem and at a great price.

First he had my car to fix the fuel pump and it took nearly three weeks. Then I didn't even have my car but a week and it started acting up again so I took it back and he has had it for 4 weeks and cannot tell me what the problem is. I went and got my car back no problems I will find another mechanic. It was the worst experience I've ever had with a mechanic and I have nothing nice to say about him

david has fixed my cars for years and has done a great job. i keep going back and would recommend him to anybody.

Master mechanic with integrity when it comes to his customers. Always does a great job and is the only person that I trust to service my vehicles. David Arnold is the best!

Found out we didn't have an oil problem, but a leaking coolant pump that the leaking coolant blew our oil sensor. We had him change our oil and he filled our coolant reservoir. Told us to keep an eye on our temperature gauge. Charged us a very nominal fee (way less than the simple oil change we had done before we left} and we finished our trip with no problems.When we tipped him for his service and kindne
