Different way to take your car

The birth of a Smart Car. The blue stripe suggests, it was a boy. :) :R

I would think due the small camper size the garage part of it becomes part of your living space when the car is removed.
I can't see myself attempting to dry it off on a rainy day to transport it. How would you keep the undercarriage clean and dry ?
I guess they would have to clean the entire floor each time .
