A local powerhouse known for its deep expertise in diesel performance and repair.

They are a top choice for owners of heavy-duty GMC trucks (Sierra 2500HD/3500HD) requiring specialized diesel and transmission work, including performance tuning and towing system maintenance.
While a Ford dealership, their highly-rated service department is a well-known and trusted local provider for all truck repairs, including GMC. They possess the advanced diagnostic tools and heavy-duty service bays necessary for complex work on engines, transmissions, and 4WD systems.

** The GMC repair market in Knoxville, IL, reflects its status as a small, rural community. There are no exclusive GMC dealerships within the city itself. The market is characterized by a few long-standing local garages and the necessity for residents to look to neighboring Galesburg for more specialized options. **Average quality** is high among the established providers, as they rely heavily on local reputation and word-of-mouth. **Competition level** is moderate; while there aren't many shops, the ones that exist are well-established and cover a broad range of services. For highly complex or warranty-related work, residents typically travel to the Galesburg or Peoria markets. **Typical pricing** is competitive with national averages but can vary significantly based on the specialist. A local shop like S & S Diesel may offer more competitive labor rates for diesel work than a dealership, while a service department like Uftring Autoworks commands a premium for its OEM expertise, tools, and warranty on repairs. For a standard service like an oil change on a Sierra 1500, expect to pay $75-$120. For specialized work like a Duramax injector replacement or an Allison transmission rebuild, costs can range from $2,500 to $5,000+, depending on the vehicle and the extent of the repair.
