This is one of the most discreet sleepers we’ve seen in recent memory, it was built by Hamburg-based coachbuilding outfit Caro International GmBH in the 1990s using a Mercedes-Benz W126 560 SEL as its starting point.
Now if you’re not particularly familiar with Mercedes of a certain vintage, the model name 560 SEL may not mean a lot to you, but when it was first released in 1985 this model was one of the fasted large saloon cars in the world.
With a top speed in excess of 250 km/h (155 mph) was ideally suited to continental autobahn duties, in fact it was one of the most comfortable and luxurious ways to carry people and luggage at speeds over 150 mph (in a vehicle without wings).
