I think the TTS is the sweet spot in Audi's TT range. You get the same engine as the Golf R, so that's 300+ hp on offer plus the security of Quattro. Standard spec is pretty good, the cabin is lovely; it's really lifted by the seats and the virtual cockpit. Reliability is very good and in terms of performance per £ the TTS is hard to beat, in my opinion. Of course, the TT RS is a step up but you're looking at £10k plus to upgrade to one of those.
