In October 1959, Berkeley introduced QB95 and QB105 models. They share engines with B95 and B105 models, but have longer and wider bodies the same dimensions as the Foursome. The wheelbase was increased from 70 inches (1800 mm) to 78 inches (2000 mm) and the track from 42 inches (1,100 mm) to 46 inches (1,200 mm). Berkeley QBs were four seaters, but very often rear seats were used as an addition place for luggage.
Berkeley QB is the extremely rare cars. The only official mention comes from Autocar Magazine from October 1959, when it appears that Berkeley’s stand featured a red soft-top QB95 and a blue QB105 with a black hard-top. So we can say, that at least 2 Berkeley QBs were built, but none are thought to have survived.
