Competition is fierce, which benefits consumers by driving a focus on customer service and fair pricing. **Typical Pricing Tiers:** * **Dealership (Greenville GMC):** Commands a premium, with higher labor rates and parts costs. This is justified by factory-specific training, proprietary diagnostic tools, and genuine OEM parts. Best for warranty, complex electronics, and newer models. * **Independent Specialists (Mauldin Tire, Mauldin Diesel):** Offer significant cost savings (typically 15-30% lower labor rates) while providing expert-level, often more personalized service. They are the preferred choice for out-of-warranty vehicles, major drivetrain work (Duramax/Allison), and performance or heavy-use applications. Consumers in Greenville have excellent options regardless of their priority: factory-perfect repairs at the dealership or cost-effective, expert mechanical work from the independents.
