Hi Olivia,

The official figures for a 2008 Astra 1.7 CDTi were 56mpg on the combined cycle and 135g/km of CO₂. I'd say you could reasonably expect it to return that kind of economy in daily driving, assuming it's one that's been reasonably well looked after and serviced regularly. Oh, just to note though - that's the figure for the basic model with 15-inch wheels. Astras with wheel sizes 16-inch and above were officially rated at 55mpg.

Hope that helps
