Customers have viable alternatives to the dealership without sacrificing technical expertise, particularly for powertrain and drivetrain issues. * **Competition Level:** High.

This benefits the consumer, as shops are incentivized to provide superior customer service and technical accuracy. * **Typical Pricing:** Pricing is tiered. The dealership typically has the highest labor rates, often 15-25% more than independents.
