Be prepared to describe the symptoms. Carry a written list of the symptoms that you can give us. Resist the temptation to suggest a specific course of repair. Just as you would with your physician, tell us where it hurts and how long it’s been that way, but let the technician diagnose and recommend a remedy. Stay involved. . . Ask questions.

Ask as many questions as you need. Do not be embarrassed to request lay definitions. Don’t rush the technician to make an on-the-spot diagnosis. You may ask to be called and apprised of the problem, course of action, and costs before work begins. Before you leave, be sure you understand all shop policies regarding labor rates, guarantees, and acceptable methods of payment. Leave a telephone number where you can be called.
