The Kadett featured a more modern design than the Volkswagen Beetle that then dominated the market for small family cars in West Germany and various surrounding countries. The Kadett offered more passenger space, more luggage capacity, and better visibility for the driver. Its water-cooled engine provided effective heating for the passenger compartment. However, by the mid-1970s the Kadett's weakness was already apparent as the car's bodywork was not well protected from corrosion.
Instead, it had the same front fascia as the Latin American Chevrolet Corsa, possibly because GM South Africa wanted the same front fascia as the sedan and pickup, as swapping with the European front fascia would have been expensive sawing and welding due to the Latin American Corsa's sharper headlights. This car was 2001 Semperit Irish Car of the Year in Ireland.
Both the driver and the front seat passenger can take advantage of the award-winning and AGR-certified (Campaign for Healthier Backs) ergonomic seats with Opel being the only manufacturer to offer such comfort in the segment (in both the Crossland X and the Mokka X). Elsewhere, maximum trunk volume of 520 liters – without folding the rear seats down – is class leading. In addition, passengers in the rear have the possibility to adjust their seating position by 150 millimeters in longitudinal direction, thus either increasing legroom or the capacity of the luggage compartment. This makes the Crossland X even more versatile.
While at the AVUS-ring, John Winter suffered a horrendous accident after being nudged by one of the Mercedes on the opening lap. He was pitched into a high-speed half-spin to the right, and hit the barriers with enough force to rupture the fuel tank. A gigantic fireball erupted from the destroyed car, but Winter was able to crawl out relatively unscathed. With only minor burns to his face, he was lucky to be alive.
The base car was available only as a two-door "Limousine" (sedan/saloon). Customers looking for a soft-top "Cabrio-limousine" would need to specify a "Kadett Spezial". For the first time Kadett buyers, provided they were prepared to choose a "Kadett Spezial" could also specify a four-door "Limousine" (sedan/saloon) bodied car, priced at 2,350 Marks as against 2,150 Marks for a "Spezial Cabrio-Limousine" and 2,100 Marks for a two-door "Spezial Limousine".
In March 2017, Groupe PSA agreed to buy Opel, its British sister brand Vauxhall and their European auto lending business from General Motors for US$2.2 billion. In return, General Motors will pay PSA US$3.2 billion for future European pension obligations and keep managing US$9.8 billion worth of plans for existing retirees. Furthermore, GM is responsible for paying about US$400 million annually for 15 years to fund the existing Great Britain and Germany pension plans.
