Unfortunately, Opel’s first victory in the DTM turned out to be as much of a fluke as the podium at Hockenheim. The Calibra’s fell behind once more, and resorted to occupying the lower end of the top 10. The airfield circuit at Diepholz, a third visit to the Nurburgring and the high-speed section of autobahn known as the AVUS-ring were all without meaningful results.
A mark of General Motors' confidence in their plans for the small car sector, and something that the Opel Kadett and the Vauxhall Viva had in common, was that the manufacturer built for each new model a completely new car plant in a region characterized by relatively high unemployment and the availability of a skilled workforce, but with no strong tradition of volume auto-making. The Vauxhall Viva was the first car built at Vauxhall's Ellesmere Port plant while the Kadett A was the first product of Opel's new purpose built Bochum plant. Ellesmere Port and Bochum would effectively become sister plants, producing subsequent generations of Kadett as well as their Vauxhall badged sisters (the Chevette and Astra) for the next fifty years.
The manufacturer now offered two versions of the Kadett, designated the "Kadett KJ38 and the "Kadett K38" the latter also being sold as the "Kadett Spezial". Mechanically and in terms of published performance there was little to differentiate the two, but the "Spezial" had a chrome stripe below the window line, and extra external body trim in other areas such as on the front grill. The interior of the "Spezial" was also better equipped. To the extent that the 300 Mark saving for buyers of the car reflected reduced production costs, the major difference was that the more basic "KJ38" lost the synchromous springing with which the car had been launched, and which continued to be fitted on the "Spezial". The base car instead reverted to traditional rigid axle based suspension similar to that fitted on the old Opel P4.
More or less by fait accompli, in the absence of the tools to build the Kadett, Opel found itself in the middle-priced bracket in Germany's postwar auto market, sandwiched between Volkswagen and Mercedes-Benz. This position was familiar to both GM and Opel, and one in which it did amazingly well. In 1953, output rose above 100,000 units for the first time since the war, and in 1954, when the sprawling plant by the Main River was considered completely rebuilt, 24,270 were employed at Adam Opel AG and 167,650 vehicles were built, an all-time high. Opel actually fully recovered from the consequences of the postwar era.
The Kadett E (Vauxhall Astra Mark 2 in the UK) wis introduced in 1984, an wis votit 1985 European Caur o the Year, lairgely due tae its advanced aerodynamic body stylin. The 1984 model wis an aa developt intae a mair conventional three-box design wi a buit (trunk), badged as the Vauxhall Belmont in the UK an the Opel Monza in Sooth Africae, launcht in Januar 1986. This wis awardit 1985 Semperit Erse Caur o the Year in Ireland.
