All I know is that I was young. I would do the oil changes, help work on the land rover and other small projects, pump brake pedals etc. Sad as now alot of teenagers cant change a flat tire, dont know where the dipstick is (not the one behind the wheel:lol etc. I work at a private school and joke that I am the schools AAA as I tend to change flats, and jump dead batteries. I try to make the kids I am helping do some of the work too for experience.
