1974 MG B - Rubber Bumper

North American regulations requested a raised ride height and polyurethane-covered bumpers required to withstand 5mph impacts without sustaining damage. Although condemned at the time by fans, the federalised MGB was actually a successful styling job compared with its Italian rivals. Later B-series engines in North America were reduced to a single Zenith Stromberg carb, emission equipment and a catalyst. Now these black bumper cars offer the best regular use practicality and value of all the MGBs.
