Up 'ere we get a TV programme called 'Shed & Buried', It's just your typical buy old stuff, do it up and flog it on for a profit type show that's popular at the minute on every channel. Although this one does have a slight slant towards Motorcycles.
Anyway, In one of the episodes (which I can't find) they find a barn full of old Landrovers including early Military types with the Rover P6 lump (?) and a basket case series 1 factory prototype with it's original Factory fitted Rolls-Royce engine. The owner refused to sell and had already turned down an offer of £40K
