Hi Marcus, I'm also new to the forum but have previously owned a TT and 2 years ago bought a 3.0 tdi convertible, had it re mapped from 240 to 296bhp, it's the steptronic auto, I absolutely love it, and as Steve says be cautious with petrol versions due to the oil usage issues, which Audi have supported well, but it put me off even considering the petrols. I can't praise the 3.0 tdi enough, buy a good one with Audi history and you cant go wrong, buy private if your confident, or take a mechanic with you, and you,ll save a few quid on forecourt prices, good luck
