hi quattro369 ... haldex isn't the only quattro system available to audi, they also use torsen, which will provide the type of FWD suggested. it's likely they'll fit this to the TT-RS.
you're right though, £50K spec'd up is far too much for a TT - in fact far too much for a Cayman I'd say - better to get a used 911.
ha ha, the old 'golf in a dress' chestnut ... that was a fair comment about the mk1 TT, but it's inaccurate in relation to the mk2 TT as anyone who knows what they're talking about can tell you. still too expensive for a TT regardless of how it's made though :o)
