The JAGUAR XJ (2015-21) 4DR SALOON LWB 3.0D V6 DPFR SS 300 EU6 LUXURY AUTO8 is a long-wheelbase, full-size luxury saloon, aimed at buyers seeking more space and refinement than a family car. In the UK, it sits among premium executive flagships, competing with the Mercedes-Benz S-Class, BMW 7 Series and Audi A8. Its 3.0-litre diesel V6 and automatic gearbox suit motorway journeys; the long cabin gives rear passengers plenty of room. It best suits drivers seeking comfort, quiet progress and a prestigious presence rather than easy city parking or bargain running costs. Distinctive styling sets the XJ apart from German rivals. mycarcheck.com records 32 checks across 10 VINs, so figures are a snapshot, not a complete market picture.
