Offer to sweep up, do the trash, etc for a local garage. Have it as a 2nd or 3rd priority after school - #1, and #2, play (socially w/art, band, theater, camping - whatever you have interest in. It's too young to narrow dwn & settle on 1 or 2 things). As U hang w/an owner and the crew try'n C if any 1 hasa interest in a mentorship relation w/U. This is how I was raised and now work at a job but restoration, problem solving and improving cars is a passion I only now have money to contribute (semi-retired). I do the same - offer brake'n muffler jobs to a friend (he gets the income) and he helps me restore an ol bronco (1966).
Ask them to show U the right way to do a tire, change oil, etc. Prove that you know safety as number one (it is a dangerous world in there). Many have insurance and leases that do not allow this type of arrangement. Most need to wait a few yrs to allow a 13 y/o in the shop - all depends on U, where U live, etc. Worth a try. Otherwise U can try a class in school (if it is so equipped). I would not enroll in a full program w/o tryin it out on 1 of these levels 1st (just a single class, volunteer at a parent's friend's place, etc)... Good Luck, let us know how U do!
