You can use the filters for our Ratings Tables to see which shops perform warranty work for car manufacturers, which indicates shops that belong to new-car dealerships.

As you can see from the figure below, when we compare dealers to non-dealers on results from our surveys of consumers and on price, non-dealers scored better across the board.

Our advice: Unless the work you need is covered by a new-car warranty or manufacturer recall, use an independent shop, not a dealership.

Except for getting free in-warranty repairs, there’s little reason to use a dealer’s repair shop. Many consumers falsely believe that dealer mechanics have access to proprietary knowledge, sophisticated diagnostic software, and better tools than independent garages. That’s not true. Both kinds of shops subscribe to the same databases that detail repair instructions, diagrams, and news from manufacturers. Although many car dealerships feature spacious, nifty-looking workstations, independents have access to the same tools and equipment.

Dealers’ quality scores may suffer somewhat because they tackle harder jobs. They argue that they get blamed for manufacturing defects, tend to work on new cars (which owners are pickier about), and get jobs too difficult for independents to handle. But after analyzing actual success rates on emissions-related repairs (as evaluated by state inspectors), we find independents perform substantially better than dealerships.
