The Buick Cascada convertible enters its sophomore year with the addition of a new trim level. The new Cascada Sport Touring, or ST, follows in the footsteps of the Enclave Sport Touring, the LaCrosse Sport Touring, the Regal Sport Touring, and the Verano Sport Touring in that it’s an appearance package and little more.

Buick hasn’t released 2017 Cascada pricing yet, but if it stays unchanged from 2016, then the ST will cost just $500 more than a top-of-the-line 2016 Cascada we tested earlier this year. Like that car, the front-wheel-drive Cascada ST features a 200-hp 1.6-liter turbocharged four-cylinder engine and a six-speed automatic transmission.
