An auto mechanic or motor mechanic

 (Australian English) is a mechanic who specializes in automobile maintenance, repair, and sometimes modification. A mechanic may be knowledgeable in working on all parts of a variety of car makes or may specialize either in a specific area or in a specific make of car. In repairing cars, their main role is to diagnose the problem accurately and quickly. They often have to quote prices for their customers before commencing work or after partial disassembly for inspection. The mechanic uses both electronic means of gathering data as well as their hands, ears, eyes and nose. Their job may involve the repair of a specific part or the replacement of one or more parts as assemblies.

 

Basic vehicle maintenance is a fundamental part of a mechanic's work in some countries, while in others they are only consulted when a vehicle is already showing signs of malfunction. Preventative maintenance is also a fundamental part of a mechanic's job, but this is not possible in the case of vehicles that are not regularly maintained by a mechanic. One misunderstood aspect of preventative maintenance is scheduled replacement of various parts, which occurs before failure to avoid far more expensive damage. Because this means that parts are replaced before any problem is observed, many vehicle owners will not understand why the expense is necessary.
