What is a normal workday like at an auto mechanic job?

During a typical workday at an auto mechanic job, a mechanic will service many different types of cars. The mechanic has to be able to evaluate a car and diagnose exactly what is wrong with it. The mechanic then has to be able to estimate the costs for the repair as accurately as possible and convey this information to the customer. Some mechanics have to go out to perform service calls, while others do all of their work in a shop environment. Most mechanics have to be skilled enough to work on all models of vehicles, but some choose to specialize in a particular make.
