I'd LOVE it if Lego made a minifigure scale 1982 VW camper just like the one which Tony Banks (the keyboardist from Genesis) owned (not sure if he still owns it). It would have all the cupboards which could be opened and closed, fabric curtains, a fridge, stove, a kettle, cups, plates, the seats could all be moved just like the real vehicle, the roof could be lifted up with the piece of material on it just like the real one and the roof and piece of material could be completely removed for easy access to the inside of the model.
*wub* x a million. :'-)
