Why These Are the Top GMC Repair Auto Repair Shops in Lyons

** The GMC repair market for Lyons residents is characterized by high quality but requires looking toward neighboring Longmont for specialized service. There are no dedicated GMC or diesel-specific shops within the Lyons city limits itself. The market in the broader region is moderately competitive, with several independent shops competing directly with dealerships on quality and price for specialized truck work. * **Average Quality:** The quality of specialized shops in Longmont is very high, with multiple providers boasting ratings above 4.5 stars. These shops have built their reputations on expertise that often surpasses the dealership experience, particularly for diesel and performance-related issues. * **Competition Level:** Competition is healthy. Shops differentiate themselves through specific niches—S & S with diesel performance, Scott's with broad-based OEM-level service, and Autoworks with a focus on customer service and electronics. This gives GMC owners clear choices based on their specific needs. * **Typical Pricing:** Pricing is premium for specialized work but generally more competitive than dealership rates. Duramax injector or Allison transmission rebuilds represent the highest end of the cost spectrum. Standard hourly labor rates are in line with the Denver-metro area, typically ranging from **$130 - $170 per hour**. A standard diagnostic fee is common ($150-$200) but is often waived if the repair is performed at the same shop.
