About Appalachian Auto & Diesel

Appalachian Auto & Diesel is a full-service automotive and diesel repair shop located on Danielsville Road in Athens, Georgia. We provide professional diagnostics, maintenance, and repair for cars, trucks, SUVs, diesel pickups, commercial vehicles, fleets, motorcycles, ATVs, and side-by-sides throughout Northeast Georgia.

Our shop is built on honest work, accurate diagnostics, and quality repairs done right the first time. We combine hands-on experience with an engineering-based approach to troubleshooting and repair — focusing on finding the root cause of a problem rather than simply replacing parts and hoping. Whether your vehicle is a daily driver, a work truck, a fleet vehicle, or a performance build, we approach every repair with attention to detail and long-term reliability in mind.

Diesel and GM specialists

While we work on all makes and models, we have extensive experience with GM vehicles and diesel trucks, including the Duramax, Cummins, and Power Stroke platforms. We also service commercial and fleet vehicles, helping local businesses keep their equipment on the road and operating reliably.

As an authorized FASS Fuel Systems and BD Diesel Performance dealer, we provide professional installation of FASS fuel systems, filtration upgrades, EGR Solutions products, and BD performance hardware for diesel owners who want better reliability, protection, and towing capability.

How we do business

At Appalachian Auto & Diesel, we believe in straightforward communication, fair pricing, and quality workmanship. You'll know what's wrong and what it costs before the work starts, and you'll get a vehicle that's actually fixed when it leaves. We proudly serve Athens, Watkinsville, Bogart, Jefferson, Commerce, Winder, Monroe, Madison, and the surrounding Northeast Georgia communities.
