Founded in 2022, Buchanan Diesel isn’t your average auto and truck repair shop. With a team boasting over 30 years of mechanic experience, our dream was to create a repair shop like no other- one with a unique approach to getting things right the first time. With a talent for repairs and an unmatched work ethic, Buchanan Diesel services a variety of vehicles, including automotive, light to medium-duty trucks, trailers, and semi-trailers for both corporate and small business fleets, owner-operators, and automotive enthusiasts alike.
