The cars were actually made by Fend's own company in the Messerschmitt works at Regensburg and Willy Messerschmitt had very little to do with the vehicles other than ruling that they carried his name. Fend's aircraft influence certainly showed itself in his desire to achieve a light yet stiff frame with low wind resistance from the tandem seating with aerodynamic steel body. This resulted in a surprisingly high performance from 175 and later 200cc single cylinder two-stroke engines. Some would say that his ultimate achievement with the Kabinenroller was the four-wheeled TG500 or 'Tiger' with a twin cylinder 490cc engine capable of higher speeds and sports car handling. However, there is little doubt that the best developed and most successful was the three-wheeled KR200. Production of the KR200 ceased in 1964.
The general handling was good but the brakes were a weak point; a non-factory conversion to front 8-inch hydraulic brakes was marketted in Britain. For use on the UK roads the side-hinged Perspex canopy still lifted & tilted to the right. The rear seat was actually a small bench-type able to hold an adult and a child. Not many were sold in Britain due to the high price. Less known is the fact that the Messerschmitt factory also produced prefabricated houses, which were designed as "self-building-kits" mainly based on an alloy frame work.
A well known appearance of this car is in Terry Gilliam's Brazil, to great effect, Cousin Itt drives a white one in The Addams Family, and a red KR200 was owned by the singer Elvis Presley. Source: Wikipedia.
