Buick Super wagon,
(1952)Buick offered woodies up to the 1953 model year. That was longer than any other American car manufacturer.
Even so, the 1952 Buick Super wagon didn't sell very well with 1641 cars produced. Its longer and more luxurious sister car, the Roadmaster wagon, was even less successful with only 359 cars produced. Pic 1 - 1952 Super wagon
