Let's face it, you probably completely forgot Buick offered a four-seater convertible called the Cascada. It was released in the US market back in 2016 as a rebadged version of the European Opel/Vauxhall Cascada but the car was never a sales success. Vauxhall discontinued its version back in 2018 and Buick followed suit less than a year later, announcing 2019 would be the final year of the Cascada in the US.

In its short, four-year life span, the Buick Cascada only sold around 17,000 units with declining sales after each subsequent model year and only 4,136 sold in all of 2018. We've known about the Cascada's inevitable death since February but according to GM Authority, it is now official.

The final example of the Buick Cascada has rolled off the assembly line at Opel's plant in Gliwice, Poland, where all of the global examples of the Cascada were built. In addition to being sold as an Opel in Europe and a Vauxhall in the UK, the Cascada was also badged as a Holden in New Zealand and Australia.

The Cascada was the closest thing to a modern Chrysler Sebring that was available on the market. With no more Sebring, the Cascada took on the mantle as the cushy, front-wheel-drive convertible primarily loved by rental fleets. But unlike the Sebring, the Cascada couldn't even find success as a rental car.

It was powered by a sluggish 1.6-liter turbocharged four-cylinder sending power to the front wheels through a six-speed automatic. The heavy convertible top hindered performance, with 0-60 mph taking an uninspiring 8.5 seconds. After the Opel brand was purchased by the French PSA Group back in 2017, we knew the Cascada (and several other Buick models) were living on borrowed time.

As a sign of how unimportant the Cascada was for General Motors, the final example has no special markings or plaques to identify it as the last one and there isn't even a photograph of the car rolling off the assembly line.
