By the sounds of things you should get an apprenticeship. I was in a similar situation but decided against a career in the motor trade because i thought i would have become bored of working on cars. so I went for an apprenticeship as an electrician/plumber and i'm now in my second year. it's quite a nice combination of the practical side - instalation, maintanence and craftmanship, Aswell as the less hands on part - Testing, inspection, regulations and problem solving. The money isn't great in the first year but after that it's ok. I've got evenings and weekends to work on cars and homers etc pay really well so they pay for most of my car parts/cars.
