It was designed and originally produced by the British vehicle manufacturing company Metro Cammell Weymann (MCW), with ownership passing to Reliant in 1989, Hooper in 1991[2] and finally Kamkorp in 2000.

The basic design of the vehicle dated back at least as far as 1970 when a prototype was caught in Westminster undergoing London trials.

[3] The overall profile of the vehicle closely matched that of the Metrocab as launched 17 years later, although the original front grille, taken from a 1970 Ford Cortina Mk II, was superseded by a more contemporary design by the time the vehicle entered production[3] using headlamps and grille from the Ford Granada Mk 2.

[7] The Metrocab featured a range of different badges, reflecting its varied ownership; originally with the MCW logo, it then featured a Reliant badge, before the full Metrocab name was displayed on the leading edge of the bonnet in a similar style to Land Rover as part of the Series II facelift.

The TTT was advertised to contain 700 improvements over the original Metrocab including new front design, new engine and the end of the fibreglass construction.
