The AUDI A4 (2008-12) 4DR SALOON QUATTRO 3.0 TDI CR DPF 240 S LINE is a sporty, premium four-door saloon, aimed at buyers wanting more refinement and grip than an ordinary family car. It sits alongside the BMW 3 Series and Mercedes-Benz C-Class in the UK used executive-car market. Mycarcheck.com records 511 checks covering 148 different VINs, giving a useful snapshot of interest in this model. Its powerful diesel engine and four-wheel drive make it appealing for long-distance commuters and families who value confident all-weather driving, while S line styling adds a sharper, more purposeful look. It offers a more engaging feel than many mainstream saloons, though buyers should balance performance and comfort against the potentially higher costs of running an older premium car. Checks show an average private-sale value of £4,000, 126,000 miles and around four previous keepers; annual use averages 8,000 miles, so compare histories carefully before buying.
