Background
The key architects of the MGB, in both roadster and fixed head guises, were John Thornley and Syd Enever. In a career arc unlikely to be seen today, Thornley was an accountant who launched the MG Car Club in the early 1930’s. By 1933 he was working with Cecil Kimber at MG and by 1959 he was the firm’s General Manager. Syd Enever had his own unlikely career path, too. He started at Morris Garages as an errand boy in 1921 at the age of 15 (and one wonders how many times he was sent to the stores for “a left handed screwdriver,” some “tartan paint,” or “a long weight / wait”), and by 1959 he was MG’s Chief Engineer and sending others for the “holes for the middle of washers.”
This pair were deeply invested in the MG marque and so delivered a successor to the MGA that was as bold as it was revolutionary. The B’s unitary construction, crumple zones and vastly improved cabin packaging truly marked it out as somewhat revolutionary for its day and a country mile ahead of the hugely popular MGA. Thornley and Enever were known to believe that the coupe bodied B GT was the more consequential of the new car’s two iterations. There was pent up demand for a hard topped coupe judging by the amount of aftermarket hard tops were sold for the “A,” but it was more than that. With its Pininfarina designed hatchback body, its pioneering use of fledgling computer aided design technologies, and meaningful luggage carrying capabilities and flexibility, this was truly a mould breaking MG.
Given this, Thornley and Enever were all for launching the GT model first with the roadster to follow along thereafter. At this time, of course, MG was a cog in the mightier British Motor Corporation machine and the suits at Longbridge saw things differently. Their calculus was that the North American market accounted for nearly 90% of MGA sales, the vast majority of those being roadsters and so the MGB Roadster should lead the charge. The MGB Roadster was launched to an appreciative press and public in 1963. The GT had to wait until the Earls Court Motor Show of 1965 to take its first bow, but it was equally well received. Its hatchback practicality, (very) token rear bench and 100mph plus top speed (by dint of better aerodynamics) made it a very desirable adjunct to the MGB range. Of course, the MGB range would go on to achieve sales in excess of 523,000 units ultimately with around 125,000 of those being hard topped GT variants making it much the rarer of the siblings.
