I drive a 120d and get about 42-43 mpg with mostly town driving and the odd long run. I love the flexibility of the engine and to be fair it revs well for a diesel. If I did little or no miles a year I would get a petrol version like the 130. I think the astras are a bit numb and looing dated. I think the focus is a much nicer car to drive and you would be disapointed at the handling in an astra. Also the sill seems to be about a foot wide which means you get a dirty leg getting in and out!
