you can learn how to wok on car and what not fairly ez now days with the net, i would say go to the metal fab class. thats nto somthing you can just read about and do, that hands on practice makes perfect. i was in auto shop in school and yea it was cool and i had a good time but i wish we had a fabricating classes. not like the regular metal tech but a automotive fab class. learning to do body work and paint and all that. thats where theres alot of money and talent.
but as said a career in this industry isnt always the best. although as long as your happy doing what you do, thats all that should really matter in the end. i would much rather not make a furtune but love what i do rather then being loaded but despise going to work every day
