The VAUXHALL SIGNUM (2003-08) 5DR HATCHBACK 3.0 V6 CDTI ELITE AUTO REV 05 is a large, five-door diesel hatchback with a premium-leaning feel, aimed at buyers wanting more room and comfort than an ordinary family hatch. In the UK used-car market, it is an uncommon alternative to estates and executive saloons, rather than a mainstream city car. Mycarcheck.com has recorded 51 look-ups covering 25 distinct VINs, a useful snapshot though not a measure of the whole market. These checks show an average private-sale valuation of £1,100 and average recorded mileage of 104,000 miles; average annual mileage is 4,000. Cars had about 4.7 previous keepers on average, so check each car’s history and condition carefully. With its V6 diesel engine, automatic gearbox and Elite trim, the Signum suits long-distance commuters, couples and families seeking relaxed, spacious travel. Its unusual hatchback layout sets it apart from Ford Mondeo and VW Passat rivals.
