My wife and I love our Cascada. We bought a premium coupe almost immediately after the car debued. We wanted a big, comfortable American droptop--a spiritual successor to a Buick Wildcat or 225 (or even a Cutlass) back in the day. Well, there were no such cars, so in 2016, if you wanted an American branded, four seat convertible, there were not many choices--this car (now gone, of course), the Mustang and the Camaro. The pony cars screamed youthful drag racer, so if you wanted a more adult ride, you went for the Buick. Otherwise, you had to shop a BMW or Mercedes.
The baby BMW 2 series was somewhat competitive in sticker price but had a tiny back seat, and the E-class Mercedes cost much, much more. And, of course, neither are US badged. (As I said, we were early adopters in 2016; if we had waited, since the car mags killed the Cascada, we could have bought the car for much, much less than sticker making it even more of a deal.)
The Cascada has a nice interior with heated, perforated leather seats and leather wrapped steering wheel (car magazines' negative reviews notwithstanding), a lovely and distinctive exterior design, a great all weather convertible top with no leaks, no drafts and minimal noise, and it feels plenty quick with the little turbo DOHC motor even though it does not put up sports car or sports sedan numbers; car magazines again notwithstanding, it is not a sporting car. The car is fairly heavy and gets poor gas mileage for a four banger, but who cares, really? We bought this to have an enjoyable, relatively luxurious convertible ride, not to be a thrifty Prius fighter.
The big issues with the car are the lack of a memory function for the driver's seat/mirror/steering wheel settings and niggles with the roof/window/seat belt presenter electrics. We had one warranty repair to this electric system but it has worked flawlessly otherwise; the one touch top mechanism is clever and a joy to watch in action as the roof is swallowed by the automatic tonneau cover. Some folks said the ride was a bit harsh. Well, since Buick specs 35 psi for the tires, I run mine at 32 psi and voila, smoother ride. I do think having an 18 inch wheel option with larger aspect ratio tires might have been a nice touch.
The car mags compared this car to the lowly Chrysler Sebring. I owned a Sebring at one time--no comparison. This Buick is a much, much better car. Buick's PR people were asleep at the switch when those first reviews were being written.
Oh, well. We all know Buick is now basically a Chinese brand and they sell quite well in China. Thanks for that, GM, since Buick is one of the classic American nameplates. I guess we'll never see a Buick Roadmaster convertible again. So sad. I'd buy one in a minute when this car gets long in the tooth....
