David,
From the dealers web page the photos say quite a bit:
Photos: 12&13 - Shut lines on bonnet to near side wing not quite correct (wings have been off)
Photos: 19 to 22 - Shows some of the restoration, the original car colour and condition
Photo: 22 - Shows original seat covers (i.e. without the red piping)
This adds up to quite major restoration from the original car which doesn't appear to have been in the best of states. If done well, fully photographed and documented by a Porsche restoration specialist then that could still be OK.
But IMHO, looking at this extended set of photos and the limited website information, there seem to be too many warning signs, as others have also suggested, to stretch to a join ownership of this particular car
