Any astra should be dirst cheap right now, I bought mine in september and i'm quite gutted now cause even 08 plates are cheaper than I bought my 07 plate for, due to the fact astra have recently announced they are releaseing their new astra in september this year.
most 08 plates in the life and design are around the 6k mark which is really good considering theyre next to new!
My astra is great, its the CDTI 1248 CC + turbo does about 340 miles to 3/4 of a tank ( i never go below the last quarter ) so i'd expect it to do about 440 to a full tank, it runs great, nice balance of comfort and sporty, lots of space, great looker, and had 3 years left on the original warrenty so it's still covered to 2010, which I can choose to extend if I wish to.. couldnt ask for more
