By 1970, the Kadett’s brief stay in the US import car rank number two was over, having been muscled aside by Toyota’s hot new redesigned Corolla (CC here). The Corolla was very much a car in the Kadett’s formula: traditional rwd and conventional in every respect. But the combination of a high D-Mark, and Toyota’s hot momentum changed the tide forever. In the US, the Corolla would soon enough depose VW out of the top slot. In Germany, the Beetles rapid crash and the Kadett’s success forced VW’s hand with the very advanced Golf, recouping the gold. The Kadett/Astra were the perennial number two in germany, but some years ago, it dropped further down the the top seller list, as smaller cars, including Opel’s Corsa have become more popular. But the Golf still sits on the throne.
As an Opel, it could've been a great rival for the Ford Probe, Mitsubishi Eclipse, Toyota Celica and all of the handsome sport coupes that popped up in the early '90s. You could get a Calibra with an all-wheel drive system, or a turbocharged engine (not from Saab), or a 2.5-liter V6 (shared with Saab). It had a hatchback for practicality. Versions with big wheels look rather handsome, too. Had it been priced like a Saab, though, it would've attracted too many comparisons with the E30 and E36 coupes from BMW at the time, and that probably wouldn't have ended well.
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.
