** The GMC repair market in the Spokane area (serving all of Eastern Washington, including any small communities like a potential "Appleton") is robust and competitive. The quality is generally high, bifurcated into two main segments: 1. **Independent Specialists:** Shops like Inland Empire Diesel and Camp Automotive dominate the high-skill, specialized repair segment. They typically offer more personalized service and often have labor rates 15-25% lower than the dealership. Their strength lies in deep mechanical expertise and building long-term customer relationships. 2. **The Authorized Dealer:** Wendle GMC provides the assurance of factory-backed repairs, which is critical for newer vehicles under warranty, complex electronic issues, and recalls. Their pricing is at the premium end of the market, reflecting their overhead and factory training. Typical pricing for a standard service like an oil change is competitive. However, for the specialized services you listed, expect premium pricing due to the required expertise and technology: * **Duramax Injector Replacement:** $2,500 - $4,500 * **Allison Transmission Service/Repair:** $400 - $800 for fluid/filter service; $3,000+ for major internal work. * **4WD System Diagnostics:** $150 - $300 (for diagnosis only). Customers in this market are well-served and have excellent options for both specialized independent repair and factory-authorized dealer service.
