Why These Are the Top GMC Repair Auto Repair Shops in Mulkeytown

** The GMC repair market serving Mulkeytown, IL, is characterized by a reliance on nearby towns, primarily Benton and Mount Vernon. Due to the rural and industrial nature of Southern Illinois, there is a high concentration of GM trucks, creating a competitive and technically proficient aftermarket service industry. The average quality of service is high, with several shops boasting decades of experience. **Competition Level:** Moderate to High among independent shops in Benton, with the Mount Vernon GMC dealership holding a monopoly on factory-direct services. Shops compete on reputation for diesel expertise and customer service rather than price alone. **Typical Pricing:** Pricing is competitive with national averages. Independent specialists like S & S Diesel may command a premium for their niche diesel and performance expertise but often undercut dealership labor rates. Dealership labor rates are highest but offer the assurance of factory certification and OEM parts. For a standard oil change on a 1500, expect $70-$120; for a complex Duramax injector replacement, costs can range from $2,500-$4,500 depending on the shop and parts used.
