Welcome. I was a similar age when i started taking a keen interest in Dubs and was 16 when i got my hands dirty helping my Stepdad with his Mk2 GTI 8v.
Be warned, if you are addicted now, then it will carry on for the rest of your life. Now 29 i havent looked back and loved every single VW i have owned (well, apart from 1 or 2).
