The Vauxhall Insignia Sports Tourer is well equipped and can be cheap to buy, but it’s not quite as spacious, refined or efficient as its rivalsread the full model review
Trim:Tech Line Nav
This would be our choice. Tech Line Nav models are the same price as SRi Nav models, just without some of the sporty details. But you still get 17in alloy wheels, auto wipers, front and rear parking sensors, dual-zone climate control, rear USB sockets, privacy glass, lumbar adjustment and an 8.0in touchscreen with in-built sat-nav. Well worth considering if you want a few more luxuries.
Engine:1.6 Turbo D 
This higher-powered version of the 1.6 diesel unit is noticeably punchier than the 108bhp option, but it has a narrower power band. Even so, the extra shove will be useful if you have a boot full of stuff.
