If you choose an EcoFlex 1.3 diesel with stop/start fitted, Vauxhall will tell you it’s capable of 72.4mpg, which is actually a pretty average number for such a car.

The EcoFlex 1.7-litre raises this figure to 76.3mpg, and lowers CO2 emissions to under the magic 100g/km mark – which would have been all very impressive a while back -  but is now humbled by the latest BlueMotion Golfs that manage official figures of 88.3mpg and 85g/km.

Good deals are available on the Astra if you dig around; be wary not to spend too much on options

The fact is that, like in so many other areas of endeavour, the Astra is little or no better than average for this class.

Among the petrol powered Vauxhall Astras, the cheaper the model the less impressive relatively speaking the its fuel consumption will be.

The cheapest 1.4 has just 85bhp and manages 51.4mpg. Compare that to its turbocharged sister that provides 138bhp at the cost of just 3.6mpg.

Residual values depend very much on what you pay for the car in the first place. Expect to be able to negotiate a substantial discount on all models save the poverty-spec, headline grabbing Expression, but expect too for it to lose more money over the course of your ownership than a Volkswagen Golf, so avoid expensive goodies that will be worthless come resale time.
