The VAUXHALL INSIGNIA (2008-14) 4DR SALOON 2.0 CDTI 160 SE NAV is a spacious, four-door family saloon from the mainstream large-car class. It offers a more traditional booted shape than the Insignia hatchback, with room for passengers and luggage, and was a practical alternative to rivals such as the Ford Mondeo and Volkswagen Passat. In mycarcheck.com data, 14 checks covered 11 distinct cars, so the sample is modest. Those records show an average private-sale valuation of £1,900 and average recorded mileage of 113,000 miles; average annual use was 9,000 miles. The cars had about four previous keepers on average, useful context when checking an individual example. The 160-horsepower diesel suits commuters and families seeking long-distance travel, with pulling power and economical fuel use. SE Nav trim adds navigation and comfort equipment, making this used Vauxhall Insignia saloon a roomy choice, though condition and service history especially matter at this age.
