The JAGUAR XJ (2015-21) 4DR SALOON 3.0 V6 SS 340 EU6 PORTFOLIO AUTO8 is a full-size luxury saloon, built to offer space, comfort and presence rather than small-car practicality. As a flagship Jaguar, it sits among the UK’s premium executive cars, competing with the Mercedes-Benz S-Class, BMW 7 Series and Audi A8. Its elegant styling and richly appointed Portfolio trim give it a distinctive British feel. In mycarcheck.com checks, this specification appeared in 16 look-ups covering 13 different VINs: a useful snapshot, though not a huge sample. Checked examples averaged £24,400 in private-sale valuation and 32,000 miles, with around 5,000 miles driven annually and approximately one previous keeper. These figures describe cars checked, not a guarantee of today’s price or condition. Its supercharged petrol engine and smooth automatic suit motorway travel; a quiet cabin and generous rear space appeal to comfort-minded buyers, though running costs merit checking.
