Dealerships offer the latest OEM training and specialized tools, while top independents provide expert, often more personalized service at a competitive price. * **Competition Level:** There is a healthy mix of national dealerships (Quirk), long-standing specialized independents (Portland Transmission), and highly-rated general repair shops (Pit Stop).
