buy an old heap of an old car, even an rs if u can stretch (is there an irony pun in that?) basic examlpe i picked up a tired S1 rst for £600 a few years back.

take it apart and do what ever level of resto you feel you can, trust me you will learn most things you need to know,

once you have the foundations and basic principles behind things you can normall use this knowledge to sus out new more chanlengine things you come across in ur mechanical past times

Nice to hear of young blood, keep the faith. cars cost you a fortune, break you heart, can kill you and be a burden. but so does everything else come to think of it!
