The price reference is the median of configuration medians, not the median of all active cars. Each configuration has equal weight. Configurations with at least 3 priced listings are used when available; otherwise the reference uses the configurations with a recorded price. Model years, mileage and condition vary. Open a model-year report below for its asking prices across all engines.

The 5.3L 12-cyl XJS: common questions

Which XJS years have the 5.3L 12-cyl?

1983–1992, without a break — 10 model years in our VIN decode, across 18 factory configurations and 1,008 VINs.

What does a 5.3L 12-cyl XJS cost?

$13,900 is a configuration price reference: the median of configuration medians, with each priced configuration weighted equally. It is not a listing-level median or a valuation of an individual car. The year-by-year ladder shows VIN and inventory counts; its links open model-year price reports covering all engines.
