High school Auto Shop class good place to start to learn basic theory, proper tool use, etc. Find something free or cheap that's not running, try taking it apart and putting it back together.

Hemmings Motor News is the publication for classic car fans. I used to subscribe, but I imagine they have a web edition these days. It is a great hobby. You can start with an less expensive model and work your way up as you go along in life.

The Velosity Channel has some great shows on car repairs and building,like Wheeler Dealer's. Find an old broken lawn mower then rebuild it to a working condition. Motors are basically motors.

I was fixing my own cars broken due to racing from the time I was 16, was helping my friends change clutches at 17, swapped my first engine by 18.

Get an old car and a Haynes manual, or something like that. If there is mechanics in shop or something like that, take it. Check out forums and web sites.

work or hang around a car shop..

find yourself an old camaro or mustang and read all you can in the car mags. car craft is one of the most informative mags out there. make friends at your local dragstrip and learn from them.

I'm only 16, but eventually I would love to rebuild a classic car. Are there any classes I should take, or books I should read, that will give me the information I need to do this?
