Vauxhall Insignia Sports Tourer review

As a lease hire shoo-in for sales reps, the most important thing for the Insignia is a strong range of diesels. And it has got that all right. There’s a bewildering range to choose from considering they’re all the same 2.0-litre CDTi. But be you fleet or private buyer, the ecoFlex options provide the best fuel returns and emit the least CO2 for those vital tax savings.
