Quite often, I see those kinds of prototypes in Copenhagen.
The cars drive on swedish test/temporary-licenseplates, and have no camo.
The models are running the current model lineup, and some of them have small pieces of camo left on the chassis.
Inside there is lots of computers and wires, and on the outside there is small black stickers with the tirepressure marked on.
What are those kind of prototypes testing for?
