Launched in 1968, the Jaguar XJ series descended from the classic S-series, popular in the late '50s and early '60s. There were four types of XJ Jaguars: the basic XJ6, the Vanden Plas XJ6, which had an extended wheelbase, the XJ12 and the XJR. The 1997 models included the XJ6, the Vanden Plas and the XJR. They were some of the first Jaguars to be remodeled after Ford acquired the company, so their reliability and affordability increased, but their plush and roomy interiors remained true to the Jaguar reputation, according to "Motor Trend."
The original manufacturer's suggested retail price for the standard XJ6 was $54,750, while the price for the Vanden Plas was $63,800 and the price for the XJR was $67,400. Kelley Blue Book prices as of October 2010 were $5,025 for the XJ6, $6,350 for the Vanden Plas and $6,625 for the XJR.
