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.
The other reason for the B’s success had to do with GM: once again, after having failed to slow down the VW’s ascent with their 1960-1961 compacts, they were forced to take the small car market seriously. That led eventually to the Vega in 1971, but in the shorter term, it meant marketing the Opel as something other than with which to remodel the garage. Now the Kadett family, which included a new fastback coupe, sedans and wagon, was seen in front of the typical American garage: two Opels for the price of one Buick.
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.
Things are a little better up front, where we find driver and passenger seats approved by the Aktion Gesunder Rucken, or German Bad Back Association. They are truly, properly comfortable, and even long journeys fail to induce numb-bum, nor thigh-tremble. It does go a bit downhill from there though. The fascia and instrument panel are pulled, more or less directly, from the Corsa hatch, which means everything’s reasonably well made, but a bit dour and glum in appearance. That contrasts sharply to the quirkier, more welcoming interiors of the Crossland’s French cousins. There are good things – the seven-inch IntelliLink touchscreen is clear and good to use, albeit it has a slightly messy menu system, but the main dials look drab, and items such as the column stalks actually feel quite fragile and cheap.
The high performance of the new Corsa GSi is complemented by the athletic exterior looks featuring large air intakes, sculptured bonnet, prominent rear spoiler and precisely modelled side sills. From the front, the bold Opel GSi fascia with large honeycomb grille and the central Opel Blitz supported by two wings, along with the exterior rear view mirror housings in carbon racing-look become visible. The large chrome-ringed design elements that are visually connected in a horizontal line via black crosspieces running across the front, along with the black traverse cleat on the bonnet support the impression of sportiness. The vibrant styling is also present when viewed from the rear. The prominent spoiler on the edge of the roof creates additional downforce, the sporty chrome tailpipe is framed by the vibrant design of the rear apron in body colour.
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
