Mini Clubman Rear Doors (It's Roomy!) Vimeo Video
 

It's huge :)

I had one for a week and it is pretty good luggage space if your a small family. There's a sort of tray in the middle of the boot which you can take out or keep there as the german had in the vid. I guess it's if you only need to have a few bags back there instead of suitcases. Kinda neat, and there are some other stuff like grocery bag holders and belts with which one can secure the luggage with.
The doors are cool too, but I'm not fond of the design. It looks too 'stretched' compared to the normal Mini when you look over the rear wheels. Other than that, it's a superb little car :)

I agree, it looks streched

I was expecting him to open the door and have a couple going at it in back.
