The Corsa Van is a car derived van based on the corresponding generation of the Corsa superminis. It first appeared in 1983, and was unchanged from the regular car, aside from the panelled rear windows (optional, glazed models were also available) and the missing rear seat. This was replaced by a flat metal loading floor. Payload of the original Corsa A is 405 kg (893 lb) and the entire range of engines was available at first.
GM imported the Opel Kadett B, built at the recently closed plant in Bochum, Germany, into North America starting in 1966. American and Canadian car buyers weren't especially enthusiastic about these cheap little cars, but sufficient quantities were sold that they were fairly easy to find in American wrecking yards through the 1980s. Here's a '67 in a Denver-area self-service yard that managed to outlive most of its contemporaries.
My dad bought a Kadett when we became a two-car family in the 60’s (Mom got the Rambler Rebel, and then a 72 Impala). It lasted until ’77, when we used the Impala to help push it down the highway and into the Olds dealership where they were having a “We’ll give you $1000 for whatever you can drive onto the lot” trade in sale. (Sadly, we got an awful 77 Cutlas Supreme). I got some of my early driving lessons (in the neighborhood) in that Opel – shifting gears from the passenger seat, or sometimes riding on my Dads lap and steering.
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.
