The MGB MK-3 `74 Roadster is a two-door sports car manufactured and marketed from 1962 until 1980 by the British Motor Corporation (BMC), later the Austin-Morris division of British Leyland, as a four-cylinder, soft-top sports car. It was announced and its details first published on 19 September 1962.
 
To meet US impact regulations, in the second half of 1974 a new, steel-reinforced black rubber bumper at the front incorporated the grille area as well, giving a major restyling to the B's nose, and a matching rear bumper completed the change.
