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.
Of the four petrol engines, the turbocharged 1.6-litre with 178bhp is worth considering, while the 1.8-litre with 138bhp is merely adequate. There's also the 217bhp 2.0-litre turbo, which is fast, and a thirsty 265bhp 2.8-litre turbocharged V6.
Four-wheel-drive versions of the 2.0-litre and 2.8-litre petrol engines are available, while automatic gearboxes are optional on the larger petrols and both diesels.
Only the entry-level ES misses out on climate control, stability and cruise controls. The SRi gets alloys, sports suspension and electric windows all round, with the VX-Line option adding an aggressive bodykit and other sporty styling cues. The SE is more comfort-orientated with alloys, auto wipers, and the Elite ups the sophistication with electrically adjustable leather seats and dual-zone climate control. The Nav editions of each trim add a large-colour satellite-navigation system.
