It combines the A8’s discreet, upmarket comfort with a powerful V10 engine and four-wheel drive, making it a distinctive alternative to a Mercedes-Benz S-Class or BMW 7 Series. mycarcheck.com has recorded 663 look-ups across 88 distinct VINs, offering a snapshot of cars being checked. The average private-sale valuation is £6,300, with average recorded mileage of 124,000 miles and annual mileage of 4,000. Checks show an average of around six to seven previous keepers, so reviewing each car’s history and condition is especially important.

Against its executive rivals, its V10 character and sure-footed traction stand out, but running costs may be substantial for owners.
