The AUDI A8 (2003-07) 4DR SALOON QUATTRO 4.2 TDI V8 SPORT TIP AUTO LWB is a long-wheelbase luxury saloon, near the top of the UK executive-car market. It prioritises comfort, space and presence over the practicality and low costs of a family hatchback or SUV. Quattro four-wheel drive, a strong diesel V8 and automatic gearbox make it a smooth, capable choice for long journeys. The roomy rear cabin suits business travel, chauffeur-style use and families seeking comfort, while its size and upkeep are less appealing for city driving or tight budgets. Against the BMW 7 Series and Mercedes-Benz S-Class, the A8 is known for understated design and a composed, premium feel. Mycarcheck.com’s modest sample—10 lookups across six VINs—shows an average private-sale value of £4,100, mileage of 135,000 and annual use of 8,000 miles.
