Top-tier independents like Precision Auto & Diesel offer competitive, often lower, labor rates while maintaining specialized expertise, particularly in diesel and performance sectors.

For a complex Duramax or Denali electronics issue, the dealership or a dedicated diesel specialist is the recommended choice despite the higher cost, while for suspension or 4WD service, a reputable independent often provides the best value.
