What is a 1979 Jaguar XJ worth today?

The Shifty Estimate is $21,900, down 13.4% over the past 12 months. That sits above the $7,075 median of actual sales because the median counts every car that sold, including high-mileage examples, while the estimate describes a clean, low-mileage one bought today. We rate confidence low: 32 public sales in a year is not enough to be firm, and the honest range is wide. Treat it as a starting point, not a valuation.

About the 1979 Jaguar XJ

The Series III XJ represents Jaguar's longest-running saloon generation, spanning 13 years of continuous refinement. While often overshadowed by its predecessors, this XJ delivered the brand's signature combination of luxury and performance in a more reliable package. The 4.2-liter inline-six produced 176 horsepower, while V12 variants offered effortless power delivery that made highway cruising sublime. Pininfarina's subtle styling updates kept the iconic silhouette fresh without losing Sir William Lyons' original elegance. These XJs featured improved build quality over earlier models, though electrical gremlins remained part of the ownership experience. Today's collectors appreciate the Series III as the last of the traditional XJs before Ford's influence. Clean examples with documented maintenance histories are increasingly sought after, particularly the final-year models with fuel injection. Values remain accessible compared to E-Types, making them an attractive entry point into classic Jaguar ownership.
