The VAUXHALL INSIGNIA (2008-14) 4DR SALOON 2.0 CDTI ECOFLEX EU5 160 SRI 6SPD is a four-door family saloon with a conventional boot, unlike the Insignia hatchback. It sits in the large-car class, where it competed with the Ford Mondeo and Volkswagen Passat, and offers useful space for passengers and luggage. With its 2.0-litre diesel engine, six-speed manual gearbox and economy-focused Ecoflex badge, this SRI suits regular commuting, motorway journeys and family trips. It is best for drivers wanting a comfortable, roomy used car with useful performance, rather than a small city runabout. The SRI trim gives it a sportier look and feel, while the saloon shape may appeal to buyers who prefer a separate luggage compartment. mycarcheck.com records two look-ups for one VIN: £1,900 average private-sale value, 116,000 miles, four previous keepers and 1,000 annual miles. This small sample offers only a guide, so check each car carefully before purchase.
