Professional and knowledgeable
These guys know diesel engines. Fixed my exhaust issue. Only minor wait for parts, but they kept me informed throughout the whole process.

Best diesel shop in town
Brought my Ford truck in for a fuel pump issue and they had me back on the road in two days. Reasonable rates for such quality work.

Saved me a lot of money
Another shop told me I needed a new transmission, but the guys at Grumpy's fixed a sensor and saved me thousands. Truly honest people.

The only shop I trust
Been coming here for years with my fleet. They are reliable and don't try to oversell you on things you don't actually need.
