Basically, I wouldn't mind learning a new skill and learning about the parts that need to be inspected / changed during car servicing, and once I get more advanced, about stuff like bodywork repairs, changing suspension, replacing exhausts etc.
I know that there are Haynes Manuals, but there's nothing like real life practice and having the various components to practice on (preferably not my own car)
Are there part-time college courses for this sort of thing? Or short courses for car mechanic novices?
