Tell me about the MGB.

The MGB is a two-door British sports car that was produced by the manufacturer MG from 1962 until 1980. The MGB was available in two bodystyles: a two seat convertible roadster known as the "tourer," and from 1967 a fastback 2+2 bodystyle known as the "GT." Most MGBs sold were of the convertible "tourer" variety. The MGB is one of the highest-volume British cars ever produced and was very popular both in the UK home market and overseas, particularly in America. The car was equipped with a 1798 cc four-cylinder gasoline engine and a four-speed manual transmission. All models were equipped with front disk brakes and rear drum brakes. The styling was modified throughout the long production run, with the most substantial change being the move from chrome bumpers to rubber bumpers midway through the 1974 model year to comply with changes in US federal automobile crash testing requirements.
