1984 Cadillac Seville problems
The Cadillac Seville is a mid-size luxury car manufactured by Cadillac from the 1976 to 2004 model years as a smaller-sized, premium model. It was replaced by the STS in 2004 for the 2005 model year.
Origin of the name
The name of "Cadillac's first small car" was selected over a revival of LaSalle or the GM design staff's preference, LaScala, primarily because, as noted by GM Marketing Director Gordon Horsburgh, "It had no negatives." The initial suggestion was "Leland" in honor of one of the make's founders but it was rejected because most buyers wouldn't understand the reference and Henry Leland had also founded rival Lincoln.
Hundreds of suggestions were considered: after extensive research, LaSalle was the top pick with St. Moritz a distant second, trailed further by Seville. A troubled past (LaSalle) and difficult pronunciation (St. Moritz) led to the eventual selection of the Seville nameplate.
Seville is the name of a Spanish province and its capital, renowned for its history and treasures of art and architecture. Cadillac had first used the nameplate for a two-door hardtop version of the 1956 Eldorado. 1960 was the last model year for the Eldorado Seville, returning in 1967 under a different name.
