Hello! The first thing employers are looking for in a mechanic is experience. The experience can come from either working on your own car or family car; Experience can also come via working at a shop and fixing actual customers vehicles. Yet another form of experience can come from working under the tutelage of a mentor or person with a lot of experience and the ability to train.
