Why These Are the Top GMC Repair Auto Repair Shops in Shelton
The GMC repair market in Shelton, Connecticut, is robust and competitive, characterized by a healthy mix of a dedicated dealership and several highly capable independent shops. The average quality of service is high, as evidenced by the strong customer ratings across the top providers. Competition is strong, which generally benefits consumers through competitive pricing and a focus on customer service. **Typical Pricing:** There is a clear pricing tier. The dealership (GMC of Shelton) commands a premium, with hourly labor rates typically 15-25% higher than the independents. However, this cost is often justified for warranty, advanced electronics, and proprietary programming work. Independent shops like Shelton Automotive and Mountain Top offer more competitive labor rates while still providing expert-level service, especially for mechanical repairs (engines, transmissions, suspension). For a standard oil change on a Sierra 1500, expect to pay $80-$120; a complex Duramax diesel injector replacement can range from $2,500 to $4,500+, depending on the shop and the specific engine.
