Buick does not build many cars like the Buick Lucerne: a 4-door sedan with 3.8 , built from 2005 to 2011 in the decade of stability control, dual-clutch gearboxes and the first serious hybrids. Its designer of record is Joel Piaskowski / John Manoogian II.
Where it came from
The Buick Lucerne is a full-size car manufactured by General Motors from 2005 to 2011. Named for the city of Lucerne, Switzerland, it served as Buick's top-of-the-line sedan until it was replaced by the second generation Buick LaCrosse.
Under the skin
Under the skin sits 3.8 other versions carried different engines, listed in the specification table below. The gearbox is a 4-speed 4T65-E automatic (V6) / 4-speed 4T80-E automatic (V8). The layout matters: the engine drives the front wheels, the packaging choice that gives a small car a big cabin. The wheelbase is 115.6 in. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
In context
Where it sits in Buick's history is not in doubt: the Buick LeSabre / Buick Park Avenue came before it; the Buick LaCrosse followed it; it was built at Hamtramck, Michigan. On a showroom list of its day it stood against the Kia Sportage, the Bugatti Veyron, the Audi Q7. Nearby in the Buick catalogue sit the Buick First Call and the Buick Funeral Car.
The money
On the used market today a Buick Lucerne typically changes hands for $10,600–$15,300, and running it — fuel and maintenance at its age — costs about $4,674–$6,329 a year. Insurance sits around $1,120–$1,580 a year. The figures are class-level estimates from the federal record, with the formula on the methodology page; the model-year pages carry complaints, recalls and repair costs year by year.
