The VOLVO S40 (2004-07) 4DR SALOON 1.6 100 S is a compact four-door family saloon, offering a booted shape, unlike the hatchbacks common in the UK. It sits in the small executive-car corner of the used market, bringing Volvo’s understated style and safety-minded reputation to buyers wanting something sensible and refined. mycarcheck.com has recorded 512 checks across 295 different VINs, a useful sample of interest in this older S40. Checks show an average private-sale valuation of £800 and mileage of 109,000, with around 6,000 miles added yearly. That points to established, modest-mileage cars suited to commuters, couples or small families. Its 1.6-litre petrol engine is a choice for everyday trips, while the saloon’s comfortable cabin and road manners make journeys pleasant. Against Ford Focus- and Honda Civic-sized alternatives, the S40 feels more grown-up and discreet, though running costs and age deserve a careful check. The average keeper count is four.
