The MG MGB Mk3 was built from 1972 to 1976.
The Roadster, the most traded version: The chrome-bumper MGB represents British roadster motoring at its purest, before safety regulations softened the design. These 1972-74 models capture the MGB's sweet spot—refined enough to be reliable daily drivers yet still sporting the classic proportions that made Abingdon famous. The 1.8-liter B-series four produces a modest 95 horsepower, but it's the car's balanced chassis and communicative steering that made it a favorite among driving enthusiasts. Wire wheels, overdrive transmissions, and factory hardtops are particularly sought after by collectors today. With over 300,000 chrome-bumper MGBs produced, they're accessible entry points into classic British motoring, though pristine examples with matching numbers command premium prices. The '72-74 years avoid both early teething issues and later emissions strangling, making them ideal candidates for weekend touring or vintage racing events.
