The first estate wagon was first offered on the 1940 Super model. It used a wooden body and was available on Buick's larger "C" series (Super and Roadmaster) in the 1946-53 model years. Then it was offered the smaller "B" body Special, Century, LeSabre and Invicta with all steel bodies from 1954 to 1964. It was reintroduced on the "B" body again in 1970 and was simply called Estate Wagon until 1977. Then it was available as LeSabre Estate Wagon or Electra Estate Wagon. The last Estates were rear wheel drive B-bodies with a 115.9 in wheelbase. The Electra Estate model name was used in 1988 and 1989 even though the Electra sedan used the front wheel drive C platform. The final year of Estate production, 1990, just used the Estate model name. The Estate was replaced with the B-body Roadmaster Wagon that same year. (edit this text)
