BMW had this classic Mini 4-door built when they launched their Mini History exhibition in Munich (soon to come to MINI Plant Oxford) and also to coincide with the launch of the 4-door F56 MINI (5-door if you include the rear hatch).

Quote from Autocar magazine:-
"As part of the exhibition, BMW has also built a replica of an experimental four-door Mini that was constructed by Austin-Morris in the early 1960s. Based on period photos, the new car is based on a later-model Mini Classic. BMW design sources say the original four-door was built on the same stretched wheelbase as the Mini Van, which was launched in 1960. One version used standard Mini front doors, which were flipped and rear-hinged, while nother version used a bespoke door design. Neither prototype survived when the company decided not to pursue the idea."

The 'Mini Story' exhibition will eventually be going on show at the Cowley Oxford Plant after its run in Munich.
