Well, the deed is done but not with the local dealer. They wouldn't budge from my car + 5.5k to change. So I rang round and sourced an alternative vehicle - very similar spec : delivery miles, dsg, leather, 5dr, steel gray, privacy glass, mfsw, parking sensors, from a dealer in Slough. Asking price was more realistic to start with so managed to settle on my car + 4k. Left a holding deposit over the phone - will view the car tomorrow to make sure its as described and then its just a case of logistics.
Still a bit shocked with myself as the decision is really heart over head, but then I have always hankered after a R32 and this is the last chance to get a new one.
Dealer claimed that this is the most busy hes been with respect to selling R32s - from my investigations the dsg variants are certainly being snapped up quick.
