Hi Dude - nice username and welcom to torquecars. I like your plan. The 1.8T is one of the most tunable engines around at the moment. The FWD only cannot cope with more than 225bhp so quattro is the way to go. Do you want reliable power or just POWER!

Get an A3 they are lighter and have 4 doors from 2000 on (although rear space is a little cramped!)
