Who is Diesel David?

Your Local Mobile Mechanic

My name is David and I am an ASE Certified Technician. In 2014, I started a truly awesome service that eliminates the frustrations of working with a repair shop. My services are 100% mobile, yup, you read that right. My customers love me, because I save the time, money, and heartache. No more waiting rooms, no more sheisty mechanics, and the best part is you get to drive your car or truck with confidence!

Imagine yourself feeling good about calling your mechanic, and never having to stress about your vehicle working properly again.

    He goes to your home or work to service your car, does good work, does it quickly and good communication like everyone else said. I've used Diesel David to replace an O2 sensor, for an oil change, and the monthly checks, headlights, battery, and fixed some major oil leaks, among other things.

    I have used Diesel David for at least the past few years now and my car has been working noticeably better since signing on to their monthly maintenance program.

    We were in the process of buying a Ford 6.0L diesel and had the Team at Diesel David do a pre-purchase inspection. They were very through and diagnosed any problems the vehicle had. The team checking bumper to bumper inside and out. This was incredibly helpful in the purchasing process as they found problems that I was not expecting! It's hard to find a good diesel mechanic, but this team is by far a GREAT diesel mechanic! Highly recommend David and his crew!

    We all know its hard to find a good mechanic. Its even harder to find a good (much less GREAT) diesel mechanic. Look no further...David and his entire team treat your truck like it's their own. Their work not only exceeds any shop I have been to in all of Georgia or Florida, they are upfront and honest when advising you during the entire job. Another thing that sets Diesel David apart is how they set the proper expectations...particularly in regards to time. You make an appointment and are frequently updated by Brendon (or one of the other guys) until your truck is ready. Whatever you need done - from minor to major - Diesel David is the only call you need to make!! (2008 Ram 3500 4WD 6.7 Cummins - 380K miles)

    I had a small problem at Diesel Davids shop and it turned into a positive experience!!..ADDITIONAL INFO January 6 2021 After reading my review Diesel Dave himself! Contacted me to hear my side of the problematic review. After hearing my problems he offered to drive my truck and check the codes after hours at no charge to see what the problem was. We went back and forth for 3 weeks before I could bring the truck in. By that time the check engine light was back on. We got together at his shop and he scanned the codes and took a bunch of time contacting Dodge and replacing a Nox sensor. He really spent a lot of busy time trying to solve the problem. I appreciate his efforts to make a bad experience as good as possible. He seems to really care about his customers and their problems! Thanks
