very good car as i work for an audi dealership i have worked on a few.
personally i would go for the face lift model the 225bhp and a better interior with xenon lights + the older ones where 210bhp. but do be carefull there are a lot of dogs out there and every 40,000mls its full service time which includes haldex oil and filter brake fluid change + the usaual plugs, air filter ect. you may fine brakes will need changing.
Also look out for front anti roll bars as the collers split on the bar an wear the bushes very common problem which is subframe off to change it.
loverly cars but if not looked after and maintained correctly wil cost you big money
