Buick does not build many cars like the Buick Centieme: a Crossover SUV with 3.6 , made in small numbers. Its designer of record is Bertone.
The story
The Buick Centieme is a concept car that was produced for the 2003 North American International Auto Show in Detroit by Buick. Its styling provided the basis for the later Buick Enclave show and production vehicles.
What is underneath
Under the skin sits 3.6 . The layout matters: drive goes to all four wheels, which is what lets the power be used on a wet road. These are manufacturer figures carried by Wikipedia and Wikidata, not road-test measurements.
Its place in the line
Nearby in the Buick catalogue sit the Buick First Call and the Buick Funeral Car.
