Last week BMW M opened their doors for a press event to show-off the new M3 Pick-up (yes it ‘s an April Fool ‘s joke) and to preview a new lightweight M3. However the most interesting part of the program was M opening their doors to secret car-park where many past prototypes are stored. Our friends at Bimmerpost were there and got some great photos of everything from an E46 M3 wagon (that sadly never went into production) to a M3 ti.

Here ‘s a quick list of the more interesting prototypes:

– E46 M3 Wagon
– E39 M5 Wagon
– E36 Ti M3
– E34 M5 Convertible
– E30 Truck
– E36 Road going M3 GTR
– E31 M8 V12 (yes the one with an early version of the McLaren F1 ‘s engine)
– E51 X5 LM (with the above engine)

Obviously it all well worth a click over to check out the pics.
