Which used Vauxhall Insignia estate should I buy?
Most buyers go for one of the diesel models, but don't rule out a smaller petrol engine if you don't cover many miles.
Of the two 2.0-litre diesels, we prefer the 158bhp version over the 128bhp model. The first is more flexible, while the second is hamstrung by long gearing. In April 2009, the ecoFLEX was launched, offering improved fuel consumption and lower emissions.
