You only live once and as you say if your still living at home with no ridiculous mortgage, council tax, insurance, gas, electric, furniture costs etc etc etc... then now really is the time to have fun and enjoy yourself, R32 - VF Charger FTW!
I'd quite fancy going down the facelifted TT 3.2 and charging that but alas I've already got all those bills so thats around £1000+ a month leaving my pocket before I even think about my car.
I was thinking about a Mk1 TT - but they're just not as practical at the end of the day. I do use the boot from time to time, and occasionally have passengers in the back, so a TT wouldn't really be any good.
