There is one on eBay £1800 at the moment... http://www.ebay.co.uk/itm/1968-RARE-TAX-EXEMPT-CLASSIC-SPLITSCREEN-BMC-CAMPER-MOTORHOME-NOT-VW-/260948180400?pt=Automobiles_UK&hash=item3cc1b93db0#ht_3613wt_146
Used to have an old ex Telecom one, the later Dodge spacewagon version with the plastic grille and built on ladder rack. Hand painted it brown Not the greatest idea ive ever had, it looked like a mobile turd ;D If I remember rightly it had a rootes 1725 engine which there are quite a few suppliers doing bits for. Sunbeam Alpine and Hillman Hunter clubs etc and the wheels I think are a Ford pattern? so bit of scope there too. I think they will be one of those vehicles that catch on and start getting silly prices like Mk1 Cortinas, Escorts and erm VW bays
