The CADILLAC BLS (2006-09) 4DR SALOON 1.9D 150 LUXURY is a compact executive saloon, offering four doors and a more distinctive alternative to mainstream family cars. In the UK it occupies a niche alongside the BMW 3 Series, Audi A4 and Saab 9-3, though it is much rarer on the road. mycarcheck.com has recorded 36 checks covering 14 different VINs, a useful but modest snapshot. These cars averaged 110,000 miles and around 7,000 miles a year; the average recorded private-sale value was £1,200. Checks also show about five previous keepers on average, so condition, service history and ownership details deserve careful attention when viewing one. The 1.9-litre diesel suits commuting and longer journeys, while Luxury trim adds an upmarket feel. It may appeal to drivers wanting comfortable saloon space and a rarer alternative to German rivals. Compare carefully: age, mileage and condition matter more than the badge when buying used.
