...don't bother knockin':

Couples in Amsterdam are writing out their dreams of passion for the chance to spend a night in a small car fitted with a bed and hoisted up on poles.

For a free overnight stay, couples must write to the Italian artist who converted the hatchback, and explain their romantic intentions -- ranging from marriage proposals to re-enactments of teenaged backseat fumblings.

My luck, the damned door would open at the just the wrong time. Explain that one to the emergency room!
