really? with a car like that I'd be worried about the amount of miles it's done, how many services has it had etc?
Just can't see anyone shopping for a 6 year old astra wanting to pay a good bit over the odds from a private seller, in a very common colour...
loads about...

etc
maybe a dealer could get that with a warranty/piece of mind, but I would say 4k tops
It's got full dealer service history, last one was done 20th of November 2013, exact mileage is 10084 but will rise as I use it daily.


mileage is king
Worth a shot
