The Buick Regal is a well-honed, pleasant sedan brought over from GM's German Opel subsidiary. As such it conveys a typically European driving experience, with a taut and steady ride, sporty handling, and excellent fit and finish. Firm, supportive seats and tight rear accommodations are another European hallmark. The base four-cylinder engine is underpowered, but agile handling tends to help make up for that. Overall fuel economy of 23 mpg is not all that impressive, however.
