In 1958, Messerschmitt launched their TG500 - a four-wheeler where the driver sat alone in the front, with one or two passengers behind. The car returned 52 mpg and was incredibly stable. The TG500 retailed for £654, including tax).
Meanwhile, the familiar Isetta came in several models, from a 300cc built in Brighton (£350) to a four-seat 600cc made in Germany (£676).
A Dutch debutante also emerged in 1958 - the Daf - which offered gearing of near-continuous variability.
