I ran across this a while back and was wondering if anyone was lucky enough to have seen one? They seem to be mostly in Sweden (Swedish company) and surrounding areas. Similar to a truck camper (which they made a version of as well) its a loft bed over the vehicle, couch and a small kitchenette. I'd love to have one on a nice Saab 9-3 like in the pic.

They made them to replace the hatches on a few models of Saab's, and two EU released Fords I believe.
And as a note: the car is squatting cause it has shorter stiffer racing springs on the rear. Its not due to the weight.
