The Kadett B was launched at the Frankfurt Motor Show in late summer 1965, The Kadett B was larger all-round than the Kadett A: 5% longer both overall and in terms of the wheelbase, 7% wider and 9% heavier (unladen weight), albeit 10 mm (0.39 in) lower in basic standard "Limousine" (sedan/saloon) form. Production ended in July 1973, with the successor model introduced a month later following the summer shut-down, in August. The two-seat Opel GT was heavily based on Kadett B components, its body made by a French contractor, Brissonneau & Lotz, at their Creil factory.
The Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
