Iain Dooley checks out Vauxhall's refined Insignia hatchback.

Engines – Don't be fooled by the modest number of diesel motors available for the Insignia, the many petrol engines might overshadow the oil-burners but the streamlined Vauxhall is most definitely a car for those who want to keep hold of their cash. One of a number of staple fleet choices, the Insignia's economy should please frugal drivers, while refinement levels are also good.

Exterior – A marked departure from the angular Vectra, the Insignia's slippery shape is a refreshing change. It's also a little bigger than the car it replaced, which is all part of Vauxhall's plan to move its mid-size offering up market.

Interior – The interior also presents occupants with a range of easy-on-the-eye curves. The overall ambience is of the premium variety, which fits with Vauxhall's aspirations. Cabin space is reasonable for a car in the class, while refinement when on the move is good – as is the amount of oddment space available.

Driving – Keen drivers might want to look away now, as the Insignia is more of a rounded performer than a B-road champion. That's okay because Vauxhall is aiming the Insignia at the premium sector, where refinement, classy looks and solid build are more important qualities. That said, the fleet-friendly diesels perform well, are quiet and frugal. The petrol motors are great alternatives if you don't rack up the miles, too.

Ownership – As with so many cars in this class, the Insignia will likely prove to be an easy car to own. It's not a car with any notable quirks or vices, and running costs should be modest – especially if you opt for a diesel. Spacious and versatile, it can double as a family car as well as a tool for business.

What to look for – Being a popular fleet choice, a full history is essential to tally mileage against servicing and repair activities. Parking dents on high-mileage cars might be acceptable but not so on a pampered, privately-owned example. A quick check of the car's paperwork would determine its history. Don't skip the test-drive as it could prove revealing if there's been any mistreatment.
