In California, the rarest Porsche Tempo Mikafa motorhome from 1955 was sold at auction. A hefty $187,000 was paid for it. 
The Porsche motorhome is indeed unique. Mikafa produced only three of these machines, and for their time, they were advanced. 
The motorhome is based on the rear-engine chassis of the Porsche 356 sports car.
The car has an opposed engine and a 4-speed manual transmission. The body is made of aluminum, and the windows are plexiglass. 
By the standards of the 50s, the Porsche Tempo Mikafa is equipped with state-of-the-art technology. For example, the interior features an Electrolux refrigerator — at the time, this was a luxury. 
There is also a kitchen with a gas stove, sofas, a folding table, and even a bathroom.
All of this is well preserved, and there is even a branded set of dishes.
