1955 Messerschmitt KR200. Correcting the shortcomings of the 175 was treated very seriously by Professor Messerschmitt when he gave the directive to build the new car. The new 200 had a wider track and cutaway fenders hiding a totally redesigned rubber-in-torsion suspension. The new larger, smoother motor was rubber mounted and the drive to the rear wheel was cushioned by a tubular shock absorber.
1954 Messerschmitt KR175. Fend Kabinenroller FK-150, it included all the elements of the first production Messerschmitts except for the plexi dome made up of several pieces, and the 150cc motor. This car is a Series 1 KR175 which is different from the Series 2 in that it has: Wiper motor can be operated by hand and the open drive chain, among other things. This car also has an original side luggage rack.
1958 Brutsch Rollera. Egon Brütsch built Four Cars for Display at the 1956 IFMA. Had a larger bench seat and a 100cc motor. In the summer of 1957, after attempting to generate interest at the IFMA, Brütsch loaded 2 "normal sized cars" with 3 Mopettas and a Rollera on the Roof and in the Trunk and drove around with his Secretary looking for someone who might be interested in producing them. Only 8 units were ever produced (licensed in France) and only Four are known to survive today.
