AutoExpress have published a Used Audi TT Mk 2 buyer’s guide for would be Audi TT owners including model specs.
“PIN down the exact spec of any potential buy. There were lots of options – some very costly. A 2.0-litre engine is all you need, but there are no weak links.
Quattro four-wheel drive was standard or an option on all models, except the 1.8 TFSI. All TTs have ESP, alloys, Isofix, climate control, and electric mirrors and windows.
Sport trim gets 17-inch alloys and a better stereo; S line spec brings sportier detailing, 18-inch alloys, lowered suspension, xenons and a multifunction steering wheel. Black Edition cars add a premium sound system, as well as a styling kit with 19-inch alloys.”
