1977 MG MGB Roadster

Description

OFFERED WITHOUT RESERVE

The MG MGB is the quintessential British sports car of its era and was made available in several different versions from its UK manufacturer, ranging from an open roadster to a three-door 2+2 coupe, along with a variety of engine sizes. 

After the MGB’s initial introduction in September 1962, numerous incremental improvements and upgrades were made until the final roadster rolled off the production line in 1980. Due to federal safety mandates, molded polyurethane bumpers — designed to handle a 5-mph crash without deforming — began to appear in 1975, and these ’70s MGBs are still among the more popular classic sports cars out there. 

The 1977 models offered optional overdrive, and the original owner of this one selected it. They were also the first MGBs with an electric radiator fan. MG, of course, emphasized the driving experience — “the wind in your hair, the road winding out before you ... Drive it and discover this rare, sensuous feeling.”
