The Fast Lane Car came across a rare sight when they spotted several Opel Cascadas testing at high attitude in the Colorado mountains. The mid-size cabriolet is normally reserved for European markets and was wearing a manufacturer plate when it was spotted, fueling speculation that General Motors is looking to bring the model overseas, possibly as a Buick.
With GM’s future plans to further align its Opel and Buick brands, the Buick-badged Cascada idea does not seem too unlikely. Automakers frequently like to test future models high up in the Colorado mountains due to the low air pressure and snowy conditions. TFLCar makes no mention of test equipment inside the car though, and unlike the test mules we usually see, it has no camouflage or any indicators that it may have something to hide.
Exactly why GM brought an Opel Cascada to America, were not sure. It does lead us to believe they are working on some type of Delta II-based convertible though, but who knows what badge it may end up with if it ever makes it to America. Check out the photos here and let us know what you think of a convertible like the Cascada coming to America in the comments.
