Well I got my fiesta 1.25 zetec a few months ago for £1200, which I think was a pretty good price considering it was also a ghia model.
Insurance wasnt too bad, after I took my pass plus, it took £500 off the premium, with final price being £1700 TFTP.
The car has just over 90k miles, but it has FSH, and there have been a few zetec engines in my family, and if they are well maintained they do last a good few miles
The key really is to keep checking the autotrader website, dont rush into anything, because at the end of the day, whats the point in getting an average car when you can wait a week and see a perfect car for a similar price
