The VOLVO S40 (2004-07) 4DR SALOON 2.0D SE SPORT is a compact four-door family saloon, offering a more premium feel than many mainstream small cars without the size of a larger executive model. It suits buyers who want a comfortable, understated car for commuting, regular motorway trips or small-family duties, with a separate boot and practical rear doors. Mycarcheck.com records show 229 look-ups covering 123 different VINs, a useful but not huge sample. The average private-sale valuation was £1,100, while cars checked averaged 137,000 miles and around 7,000 miles a year. The recorded average of about five and a half previous keepers suggests many examples have changed hands several times, so check each car’s history and condition carefully. Its 2.0-litre diesel suits long-distance use, while SE Sport adds a sportier look. Against rivals such as the BMW 3 Series and Audi A4, it offers restrained Swedish style and appealing value.
