When you bought your car, you did your homework: Consulted independent reviews. Checked reliability ratings and crash-safety findings. Pondered the value of all the gadgets. Compared trunk space and legroom. Test drove it. Bought through Checkbook's CarBargains service, which means you practically stole the thing.

Unfortunately, that other driver—or your own temporary distraction—didn’t match your diligence in buying the just-right ride. While even the best body shops can’t undo the accident, our ratings reveal they can undo the damage and restore your car to its pre-accident appearance and performance. But our ratings also reveal that some shops may compound your misery with lousy work. And that prices at some shops are more than twice as high as their nearby competitors.

Auto bodywork is difficult to do well. Since any blemish shows on the smooth skin of a car, even ordinary tasks like patching rust spots or blending paint are challenges. Below the surface, precision is equally critical—with an error of less than 1/16 inch in the adjustment of a modern car body frame capable of affecting performance.

Bodywork doesn’t require exacting work standards alone. Mechanics also must possess expertise on the properties of metals and plastics; the mechanics of high-tech suspension and steering systems; modern welding methods; the art of paint tinting and blending; how to spot accident-related damage to mechanical, electrical, air-conditioning, and other systems; and much more.

To find a shop that provides top-quality repairs, check several points.

Ratings from Customers

Our Ratings Tables report how area body shops were rated by their customers. We surveyed area consumers (primarily Checkbook and Consumer Reports subscribers) and asked them to rate shops they’ve used as “inferior,” “adequate,” or “superior” on questions such as “doing work properly,” “promptness,” “letting you know cost early,” “advice on service options and costs,” and “overall quality.” Our Ratings Tables report the percent of each shop’s surveyed customers who rated it “superior” (as opposed to “inferior” or “adequate”) on each of these questions. We also report the percent of surveyed customers who rated each shop “adequate” or “superior” (as opposed to “inferior”) for “overall quality.” Click here for detailed information about our survey and other research methods.

Many of the shops were rated quite high by their customers. Several were rated “superior” for “overall quality” by more than 95 percent of their surveyed customers. But at some shops, things didn’t go so well. Some shops were rated “superior” overall by fewer than 65 percent of surveyed customers, with customers often complaining about delays and shoddy work.

Complaint Records

In addition to ratings from customers, our Ratings Tables show counts of complaints on file with local government consumer protection offices for a recent two-year period and complaint rates relative to the volume of work shops do. Click here for more information on reported complaint counts.

Communication with Insurers

If an insurance company is paying for repairs, you want a shop that can make an articulate case for the repairs you need. Does the shop provide a clear estimate? Can its representative explain and document the need for each element of the job? If so, chances are good that the shop will get your insurance company to pay for all needed work.

Experience with Your Model of Car

While most good body shops are capable of repairing a wide variety of cars, make sure the shop has experience working on yours. Even some highly popular domestic car models now require expertise or special equipment to repair.

Certifications

The National Institute for Automotive Service Excellence (ASE), a nonprofit organization that certifies auto mechanics, also tests and certifies auto body technicians. ASE’s Collision Repair and Refinish Test Series evaluates mechanics on four types of work: painting and refinishing; nonstructural analysis and damage repair; structural analysis and damage repair; and mechanical and electrical system repair. ASE also tests and certifies individuals for skills in analyzing damage and completing estimates.

To become ASE-certified, a technician must pass one or more of the collision repair exams and present proof of two years of relevant work experience. Those who pass the three collision repair tests plus the painting and refinishing test become ASE-certified Master Collision Repair Technicians. To remain certified, technicians must be retested every five years, which forces them to keep up with changing technology.

Many shops display plaques bearing the names of their ASE-certified technicians and dates of certification. To check for certification if you see no such plaque, ask to see a technician’s credentials.

We asked each shop if it employed at least one ASE-certified technician. It turns out that shops employing certified technicians do not have higher customer-satisfaction levels than shops with no certified technicians—which is not surprising since the proportion of certified technicians at most shops is low. Nonetheless, we still believe it’s worth requesting that a certified technician work on your car. Among the shops on our ratings table, repair prices at shops with certified technicians were comparable to the prices of shops with no certified technicians.

The ASE Blue Seal of Excellence Program recognizes shops at which at least 75 percent of technicians are ASE-certified and at least one mechanic is certified in each area of service the shop offers. Blue Seal shops are reevaluated annually to determine if they still qualify for certification. Look for an ASE Blue Seal of Excellence plaque at a shop you are considering for repair work. To find Blue Seal shops, check www.ase.com.

Also ask to have your vehicle repaired by a technician who has completed training offered by I-CAR (Inter-Industry Conference on Auto Collision Repair), a not-for-profit organization comprised of body shop owners, insurance companies, automobile manufacturers, and parts suppliers. I-CAR offers a multipart collision repair program, which includes training on restoring damaged vehicle panels; straightening structural damage; repairing heating, cooling, and air-conditioning systems; welding; corrosion protection; refinishing; glass replacement; repairing electrical systems; and fixing steering and suspension systems, among other subjects.

I-CAR awards its Gold Class designation to businesses that have met a specified level of training. To find a Gold Class repair shop, check the directory on I-CAR’s website.

We asked each shop if it employed at least one technician certified for completing one or more I-CAR training courses. As with ASE, shops that employed I-CAR-trained technicians did not receive higher customer ratings than shops with no I-CAR-trained mechanics on staff.

Protections

Ask the shop to show you proof that it carries a current liability insurance policy and that it is bonded.

Also, look around the property to make sure your car will be secure while stored there.

Source of Parts

Ask about the source of any parts that will be used. Shops can use new original equipment manufacturer (OEM) parts, aftermarket parts from independent parts manufacturers, or used parts. OEM parts are usually the most expensive option, which is why insurers often push shops to use less expensive aftermarket or used parts. There is some concern over the quality of non-OEM aftermarket parts, which we discuss in the article below.
