The article dives into MGAs

The MGA's design was loosely based on a factory-built race car for a privateer running the 24 hours of Le Mans in 1951, that was scrounged up using MG TD mechanicals by Syd Enever, who joined the company in the 1920s at the age of 14

The MGB was ultra rigid, a unibody, and MG's monocoque car, and resulted from contributions from Syd Enever.

The MGB GT had a sculpting assist from Pininfarina

SAIC Motor of Shanghai bought MG in 2007 by acquiring Nanjing Automobile Corporation (NAC), which had bought the brand from the defunct MG Rover Group in 2005. Currently, MG operates as a division within SAIC's passenger vehicle branch.
