The 1958 Buick was marketed beginning in September 1957, just as the [[space age]] began with the launching of [[Sputnik I]] on October 4 of that year. The "Sweepspear" evolved into the [[Car tailfin|"Delta Fin"]] reminiscent of a [[rocket ship]], which appeared on the all-new appearance for 1959, and was trimmed down in 1960 and removed for 1961.<ref name="flory 50s">{{cite book |last=Flory |first=J.
