The competition is healthy, creating a market where shops must demonstrate proven expertise to succeed. **Average Quality:** The quality is generally high, with several shops boasting specific certifications and decades of experience. Customers have a clear choice between the OEM dealership for factory-specific issues and highly specialized independents for diesel and transmission work. **Competition Level:** Moderate to High.
