The average quality of these top-tier specialists is very high, as they survive and thrive on reputation and word-of-mouth in a tight-knit community. Competition is strong on the basis of technical skill and customer service rather than price. Pricing is typically fair and competitive for the region, often lower than dealership rates but reflective of the high level of expertise required. Customers generally expect to pay for quality diagnostics and genuine or high-quality aftermarket parts. For major diesel or transmission work, residents of Isom are willing to travel the short distance to Hazard or Whitesburg to access the necessary specialist knowledge, making these three providers the de facto top choices for comprehensive GMC service.
