3.8.3. Coordination of cost of works
Ask about the approximate cost of works and materials before you give a final task for repair. Accurately discuss border of increase in cost in need of additional works.
Ask about diagnostics cost. For example, if it is necessary to reveal why your car spends too much fuel or badly disperses or why you hear extraneous noises.
Leave to car service a phone number on which it is possible to contact you if during repair there are questions demanding coordination with you. Record your decisions in writing.
Ask written preliminary accounting of works and services, and after their end — the detailed account. The account of car service should not exceed preliminary accounting more than for 20%.
