Vehicle repairs cost an average 34 percent more at new car dealerships than at independent repair shops, according to a first-of-its-kind study just released by the Automotive Aftermarket Industry Association (AAIA).

The study reveals differences in the costs of parts and labor between domestic and import vehicle nameplates and from city to city. Per the study, consumers in Los Angeles pay as much as 46.8 percent more at dealerships than independent repair shops for repairs. The cost to consumers of specific repairs also varies widely. For example, researchers discovered the average cost for radiator repair for a foreign nameplate vehicle, including parts and labor, is $325.99 higher at a dealer than at an independent shop; and the cost to purchase and install front brake pads on a foreign nameplate vehicle is $138.92 more at a dealer than at an independent shop.

AAIA's Vehicle Repair Cost Analysis: Comparing New Car Dealerships vs. Independents looksat the parts and labor costs of 10 vehicle repair jobs for domestic and foreign nameplate vehicles in six cities across the country, including Boston, Newark, Atlanta, St. Louis, Los Angeles and Seattle.

Highlights of the study include:

• Vehicle repairs for parts and labor averaged 34.3 percent more at new car dealers than at independent repair shops.

• Foreign nameplate repairs performed at dealers averaged 36.8 percent more than at independent repair shops while repairs performed on domestic nameplates averaged 31.5 percent more at dealerships than at independent repair shops.

• Total 2008 cost difference for consumers having repair work performed at car dealers rather than independent repair shops for the 10 jobs equaled 11.7 billion.
