The North American MGB Register was formed in late 1990 as the result of a strong demand for a non-profit, democratic organization which would be run by MG enthusiasts, for MG enthusiasts. Each and every member would have a voice on policy. The officers would be elected by the membership and would offer them selves for re-election at the Annual General Meeting. .The finances of the REGISTER would be open to all, at any time. The North American MGB Register would be dedicated to maintaining and expanding interest in Britain’s most popular sports car .. the MGB. The North American MGB Register membership would be open to all, with no restrictions, and where the ownership of an MGB is not a condition of membership. Activity, Enthusiasm and Dedication are cherished.

At the foundation meeting, attended by enthusiasts from three continents, it was agreed that the MG Midgets and the MG 1100/1300s would be welcomed into the North American MGB Register and would be actively supported by their own sub-registers. More recently, post 1980 MGs like the RV8, MGF, MGTF & MGC have been welcomed as well and their own sub-registers established.

NAMGBR also sought and gained the approval and support of the MG Car Club of England, the original and oldest of all MG clubs. Consequently NAMGBR is the only national MGB organization in the United States, Mexico and Canada officially sanctioned by the MG Car Club. NAMGBR is also affiliated with the MG Owners Club of England.
