So I flew up to look at it and it wouldn't start! Talk about sods law... Apparently the crankshaft sensor needs to be replaced and PK need to order one in.
Massively disappointed as that was the reason for me coming up but at least I've got to see the car in person and it is in quite good nick apart from a few minor cosmetic things which I can take care of.
The dealer will get the sensor replaced and so I've agreed to pay the deposit without hearing or driving it (hopefully I won't come to regret that decision!)
Now I have a 2 hour wait at the airport for my flight back
