Simpson itself has limited options, with one primary general repair shop (Simpson Auto Repair) that handles most local day-to-day service needs. For specialized services—particularly for Duramax diesel, Allison transmissions, and advanced electronics—residents reliably travel to McPherson, the county seat located approximately 15 miles away. The competition level in McPherson is healthy, featuring a mix of specialized independent shops and a long-established dealership. This provides GMC owners with clear choices: specialized independents for powertrain expertise and often lower labor rates, and the dealership for OEM-level diagnostics, luxury feature repair, and warranty work. Pricing is generally competitive for the region, with labor rates typically below those of major metropolitan areas. The overall quality of service available to Simpson residents is high, thanks to the proximity of McPherson's robust automotive service market.
