It does seem a bit pricey, but from the pictures the bodywork looks very straight and original. If the bulkhead is not too bad and especially if that bodywork is not full of filler, then I'd try and negotiate a lower price for it. It looks superficially bad, but if that paintwork is good underneath all that grime it would be a major plus point. Unmolested Series IIs and IIAs are quite rare now and that looks to me like it could be made into a really nice one with a new chassis and a general overhaul.
