Shops differentiate themselves through specialization (e.g., diesel performance), broad general expertise, or convenience. This forces businesses to maintain high standards of customer service and technical capability. * **Typical Pricing:** Labor rates are competitive with the broader North Jersey region. Expect to pay between $120 - $160 per hour for labor. Specialists like diesel or transmission shops may command a premium due to their advanced tools and training.
