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.
