Question: What General Motors car model name used by Buick for a line of upscale performance cars from 1936 to 1942 and 1954 to 1958, and from 1973 to 2005 for a mid-size car, can be described as a scraper?
Sentence (from "Buick LeSabre"): The name originated with the 1951 GM Le Sabre show car designed by Harley Earl; that car is often mistakenly attributed to the Buick division, but in fact it was presented as a GM vehicle without reference to a specific GM division.
Relevant evidence: No
