Buick knows that, sometimes it’s more fun to drop your top—hence the Buick Cascada. A 1.6-liter turbo four makes 200 hp; front-wheel drive and a six-speed automatic are standard. Despite its sleek looks, the Cascada weighs almost 2 tons, which hinders performance. In our test, it took 8.3 seconds to hit 60 mph—much slower than its competition. More important is that the soft top can drop in 17 seconds and at speeds of up to 31 mph. Trunk space is 13.4 cu ft with the top up and 9.8 with the top down.
