Hard to say, as it was part of a combined trade in with a 3 year old TT roadster against a TT of £34k
I declined the initial offer of £20k, and they came back and reduced the price to change by a further £1800, so I got the equivalent of £21,800. Some of that may be a reduction in the cost of the TT, I guess. Quite how they are putting the various sums through the books, I'm not sure
