The AUDI A8 (2007-10) 4DR SALOON QUATTRO 3.0 TDI V6 233 SPORT TIP AUTO is a large, premium four-door saloon, sitting among the UK’s flagship executive cars rather than everyday family hatchbacks. Its understated styling, spacious cabin and automatic transmission make it suited to comfortable long-distance travel, business use and buyers wanting a refined used luxury car. Mycarcheck.com recorded 294 checks covering 115 VINs, giving a snapshot of cars searched. The average private-sale valuation was £4,900, while recorded mileage averaged 144,000 miles; annual mileage averaged 8,000. These figures suggest many are now higher-mileage older cars, so check service history and condition carefully. The average was nearly six previous keepers, making a vehicle-history check particularly worthwhile. The 3.0-litre diesel and four-wheel-drive Quattro system give the A8 a confident, relaxed feel, and it is a more discreet alternative to a BMW 7 Series or Mercedes-Benz S-Class. Running costs can be substantial.
