The way it nearly came to the US is interesting, though. Back then, GM North America was a very different place than GM Europe, and it looked like there was very little interest in bridging the gap, unlike today. But after GM bought a 50% stake in the Trollhattan trolls, the General was now burdened with the problem of attracting more than devotees to an aging lineup at dealerships. The solution was to sell the Calibra to Americans through Saab dealerships, but badged as a Saab.
The suspension and brakes got some serious attention too, and the Rally 1900 was quite the sensation in its brief heyday, and garnered a very positive review by Car and Driver. (see related story on C/D’s Opel Kadett assassination story). Until the Ascona/Opel 1900 (CC here) came along in about 1971, the Rally carried a bright flame for Opel. The Ascona had been planned as a replacement for the Kadett, but when Ford launched their very bare-bones Escort, Opel kept the Kadett on, although at least in the US, it reverted to a very basic trim level and only with the 1100 cc motor, and sales swooned, due to rising prices as a result of the falling dollar.
Just a year later, a new Soviet car, the Moskvitch 400, rolled off a Moscow assembly line. It seemed to be the Opel Kadett in every detail, with only the name changed (various sources provide contradictory information; see the respective article). By late 1950, the Russians were exporting these Kremlin Kadetts to Belgium, stressing in their promotion that spare parts could easily be obtained from Germany. A Moskvitch model that bore no trace of Opel engineering was not introduced until 1959, and by that time, Opel was just about ready to introduce a new Kadett of its own.
In 1924, the Rüsselsheim-based company went even further to cater to the “average consumer” – also thanks to an automotive innovation. After all, from the very first minute Opel was committed to producing cars as efficiently as possible and thus making them affordable for a broad customer base. Consequently, the 4/12 hp heralded the start of assembly line production in Germany. And because the 60 km/h fast car was only available “in a quiet green that pleases the eye” to keep the time and effort required for production at a minimum, everyone called it the “Tree Frog”. Soon, 25 two-seater “cars for everyone” left the assembly line every day. In the following years an entire vehicle family was built on the Tree Frog technology. The smoother production ran, the greater the cost advantage that Opel passed on to its customers. Unbelievable but true: the purchase price of the 4 hp model series, of which 119,484 units were produced, was almost 40 per cent lower in 1931 than at the launch of the Tree Frog model.
