Widely regarded as the premier specialist for diesel and 4x4 trucks in the Valley.

They are a go-to for heavy-duty owners who use their trucks for serious towing and off-road applications.
A long-standing, family-owned shop known for its master-level technicians and commitment to dealer-level diagnostics without the dealer price.

** The GMC repair market in Tempe is competitive and of generally high quality, benefiting from its proximity to a major metropolitan area (Phoenix) and a climate that is demanding on vehicle cooling and electrical systems. The market is segmented into three primary tiers: 1. **Dealership Service Centers:** Offer the latest OEM tools and training but at a premium price. They are best for warranty work and very new model-specific issues. 2. **High-End Specialists (like RPM Diesel):** These shops dominate the niche for diesel, heavy-duty, and performance-oriented repairs. They often attract customers from across the Phoenix metro area due to their specialized expertise, and their pricing reflects this high-demand, specialized knowledge. 3. **Established Generalists with GM Expertise (like Certified Auto & TransTempe):** These shops form the backbone of the market, providing reliable, high-quality service for the broadest range of GMC vehicles at a more accessible price point than dealers or ultra-specialists. They succeed through reputation, longevity, and deep community roots. Typical labor rates in Tempe range from **$130 - $180 per hour**, with specialists commanding the higher end. The presence of Arizona State University and a large commuter population ensures a steady demand for service, pushing shops to maintain high standards to remain competitive.
