Look for shops that display various certifications - like an Automotive Service Excellence seal. Certification indicates that some or all of the technicians meet basic standards of knowledge and competence in specific technical areas. Make sure the certifications are current, but remember that certification alone is no guarantee of good or honest work. Ask if the technician or shop has experience working on the same make or model vehicle as yours. Ask how the shop prices its work before you arrange to have any work performed.
Some shops charge a flat rate for labor on auto repairs.
This published rate is based on an independent or manufacturer's estimate of the time required to complete repairs. Others charge on the basis of the actual time the technician worked on the repair. If you need expensive or complicated repairs, or if you have questions about recommended work, consider getting a second opinion. Find out if there will be a diagnostic charge if you decide to have the work performed elsewhere. Many repair shops charge for diagnostic time.
