Auto repair in the United States is split between independent shops, dealership service departments and national chains. Independents handle most routine work (oil changes, brakes, tune-ups, check-engine diagnostics) at lower labor rates and often specialize in one make or in imports; dealers keep factory tools, software and warranty authority; chains sell speed and standard pricing on maintenance items. Most shops charge a diagnostic fee, credited toward the repair if you go ahead, and quote parts and labor separately. Certification matters: look for ASE-certified technicians and, in many states, a state repair license posted at the counter. Written estimates are required by law in most states before work begins, and you are entitled to your old parts if you ask.
