The AUDI A8 (2007-10) 4DR SALOON QUATTRO 4.2 TDI V8 326 DPF SE TIP AUTO LWB is a full-size, long-wheelbase luxury saloon, sitting near the top of the UK executive-car market. It offers generous rear space and an understated alternative to a Mercedes-Benz S-Class or BMW 7 Series, with four-wheel drive and a powerful diesel engine for relaxed, confident journeys. Mycarcheck.com has recorded 21 checks covering 10 distinct VINs, a useful snapshot rather than a measure of the whole market. These records show an average private-sale valuation of £7,200, average recorded mileage of 116,000 and annual mileage of 5,000. The cars had about 3.6 previous keepers on average. This A8 suits drivers wanting motorway comfort, generous rear space and performance, rather than cheap motoring or easy city parking. Its refined cabin and long-distance diesel ability distinguish the Audi A8 4.2 TDI, but buyers should check service history and running costs.
