Launched in May 1962, the B was only initially available in Roadster form - the hatchback GT derivative not being offered until 1965. Suspension was by wishbones and coil springs at the front, and a live axle mounted on leaf springs at the rear. Damping was by lever arm units all round. Braking was by discs at the front and drums at the rear. At launch, the model was powered by a three-bearing version of the 1798cc B-Series engine that produced 95bhp at 5,400rpm. However, with an eye on superior reliability, this unit was replaced by a five-bearing one two years into production. The newcomer's monocoque construction resulted in weight savings over the outgoing MGA (it tipped the scales at 2028lb), reduced manufacturing costs and notably tauter handling. The MKII model of 1967 brought an updated manual gearbox with revised ratios and synchromesh on all gears, as well as the option of a Borg Warner automatic unit. Other changes included a revised rear axle and a switch from dynamos to alternators. In 1969, Rostyle wheels replaced the previous pressed steel version for standard fit. With the MKIII derivative of 1972 came a new facia and improved heater. However, the biggest visual change in the car's history occurred two years later when steel reinforced rubber bumpers replaced the chrome ones and the ride height was raised by one inch. These changes were demanded by the American market, which had accounted for much of the car's production from day one. By the time Roadster production ceased in 1980, a total of 399,070 are said to have been produced, a large proportion of which are still providing good service today.

The Roadster 'ONL 646X' was first registered in 1981, suggesting it must have been among the last of the MGBs produced. Its sports Yellow bodywork allied to a Red-piped Black leather interior. Its standard engine is mated to the desirable overdrive gearbox and steering is achieved via a woodrim wheel. There is also a boot rack for increased luggage capacity. The vendor has owned the B for the last ten years and regards its bodywork, paintwork, trim, engine and gearbox to all be in "good" order.
