The closest Buick reaches an outdoor vehicle, Regal is powered with a supercharged version from the 3.8 V6 in the most widely used GS specification (although a naturally-aspirated LS variant can also be offered) and includes suspension settings which are the firmest the brand’s engineers feel is going to be acceptable to its buyers.
Dual zone heating and cooling, leather and wood and a lot of high-perceived-value chrome all increase the sense this car cannot decide between as being a limousine or perhaps a sports utility vehicle.
The conservative body styling increases the confusion, and also the overall impression is the fact that nobody knows which sector from the market this car is pitched at.
