Opel cars appeared under their own name in the US from 1958 to 1975, when they were sold through Buick dealers as captive imports. The best-selling Opel models in the US were the 1964 to 1972 Opel Kadett, the 1971 to 1975 Opel Manta, and the now-classic 1968 to 1973 Opel GT. (The name "Opel" was also applied from 1976 to 1980 to vehicles manufactured by Isuzu (similar to the "Isuzu I-mark"), but mechanically those were entirely different cars).
the Chevy Chevette, while a MUCH better car than the Vega was at the time, and even now, that’s not saying a whole lot, other than it WAS infinitely more durable and longer lasting and reliable than the Vega, though by ’76, the Vega was decent enough, but the damage was done. I know as my Mom drove a ’76 Vega from roughly 78-83 with the only major thing being the carb being rebuilt around 1980. The Chevette was basically a redesigned Kadett/Vauxhaul Chevette.
On the British motoring show Top Gear, Richard Hammond drove a 1963 Kadett A through the middle of Botswana and across the Makgadikgadi Salt Pan. He loved the car so much that he named it Oliver and later had the car shipped to the United Kingdom and restored, and it remains in his possession. It appeared on Richard Hammond's Blast Lab with the personalised number plate 'OL1 V3R'. It also appeared in the Top Gear lorry challenge as one of the used obstacles.
After the Second World War the Soviet Union requested the tooling from the Opel Rüsselsheim car plant in the American occupation zone as part of the war reparations agreed by the victorious powers, to compensate for the loss of the production lines for the domestic KIM-10-52 in the siege of Moscow. Faced with a wide range of German "small litrage" models to choose from, Soviet planners wanted a car which closely followed the general type of the KIM – a 4-door sedan with all-metal body and 4-stroke engine. They therefore rejected both the rear-engined, two-door KdF-Wagen (future VW Beetle) and the two-stroke powered, front-wheel-drive, wooden-bodied DKW F8, built by the Auto Union Chemnitz plant in the Soviet occupation zone. The closest analog of the KIM to be found was the 4-door Kadett K38.
It had some crazy mechanical issues. At one point it stumbled and stalled because the carburetor had come loose from the intake manifold and I had to tighten it back down! Another time, my brother was driving it and the brakes failed. Somehow the end of the brake shoe that meets the brake cylinder piston had become worn on one side, causing the piston to slip off the end of the shoe when the brakes were applied, losing braking and squirting fluid all over.
