I like the "idea" of mechanic work: replace this broken part with a new part, and have a nice new working vehicle! Simple!!
......but in practice........it seems there is ALWAYS an additional skill set, a speciality tool that I need that I don't have (looking at you Hemi motors and your 16 fancy spark plugs with the one that you cant get to), and vast vehicle mechanical knowledge that, evidentially, some people are naturally born with (missed me

)!
With all of that said, I do like working on vehicles, and fixing them myself. Just get owley after some jobs!!
