The CADILLAC BLS (2006-09) 4DR SALOON 1.9D 150 LUXURY AUTO6 is a four-door, mid-sized executive saloon: a more unusual choice on UK roads than a BMW 3 Series, Audi A4 or Mercedes C-Class. It pairs a 1.9-litre diesel with an automatic gearbox and well-equipped Luxury trim, aiming for comfort and distinction. The mycarcheck.com sample is small—15 checks covering 10 different VINs—so it is a useful snapshot, not a full market picture. Checks show an average private-sale valuation of £1,300, average recorded mileage of 101,000 miles and about 5,000 miles a year; cars had 4.6 previous keepers on average. This BLS suits commuters and drivers covering longer journeys; its automatic can ease traffic, while the boot may suit a small family. The diesel aims for sensible fuel use, and distinctive styling offers an alternative to mainstream rivals. At this age, check service history, condition and gearbox operation carefully, judging each used car individually.
