The spacious Buick Lucerne is comfortable for all but the tallest of passengers, while offering rich interior materials and a luxury-car feel.
“Compared with the previous generation Park Avenue known to so many Buick loyalists, the Lucerne offers an inch more rear legroom as well as more supportive seating,” says Kelly Blue Book. “Only taller riders might wish for more head clearance,” reports Consumer Guide. “Legroom is good, but foot space is tight. Some testers say the seat is too low for best support. Three-across travel is complicated by an uneven floor and cushion shape. Large door openings make entry and exit a breeze.”
According to Cars.com, "seating for either five or six occupants is available," depending on the style of front seat. Edmunds reports that "the Buick Lucerne comes standard with seats for five, but a split front bench seat can be ordered on the lower-level for six-passenger capacity...room is abundant in any position, though seat comfort is only average."
Consumer Guide notes that Buick Lucerne "[trunk] lid hinges intrude into the cargo area," and a "small rear-seat pass-through is a poor substitute for folding seatbacks." Meanwhile, the Lucerne’s "interior storage is subpar due to a small glovebox and door map pockets." Cars.com states that "the trunk holds 17 cubic feet of cargo."
The Lucerne's luxurious interior is marred by the use of cheap plastics. “Cabin materials are mostly of high quality, but a few lightweight plastic panels seem out of place given Lucerne's pricing,” says Consumer Guide. “The Super benefits from a leather-covered dashtop and upgraded trim more befitting the car's near-luxury status.” Edmunds comments that "there are still a few low-grade plastic pieces thrown into the mix, and fit and finish needs improvement."
Consumer Guide says that 2009 Buick Lucerne vehicles "were impressively quiet." Autoblog reports that all 2009 Buick Lucerne models are "are built with an exclusive engineering process called QuietTuning to reduce, block and absorb noise from entering the interior.”
