The CADILLAC BLS (2006-09) 4DR SALOON 2.0T 175 SE is a four-door, mid-sized executive saloon for buyers wanting something more distinctive than a mainstream family car. In the UK it sits in the same broad territory as the Saab 9-3, BMW 3 Series and Audi A4, but its Cadillac badge and relatively rare presence make it an unusual alternative. Its 2.0-litre turbocharged petrol engine gives the BLS a more spirited character than a basic runabout, while the saloon layout suits commuting, longer journeys and small-family duties. It may appeal to drivers who value comfort, a smart traditional shape and individuality over familiar choices. Check condition and running costs carefully, as with any older premium car. mycarcheck.com records seven checks across six VINs, a small sample. Average private-sale value was £1,400; average mileage was 101,000; annual use was 7,000 miles; vehicles each had nearly four previous keepers on average.
