1.2 16V (2003) here on 22k, had it from new. Get 46mpg on my 10 mile through-town daily commute.
Oddly enough the few times Ive really gone for it (usually down to and around the south coast, about 130 miles a day) Ive returned mpg figures in the 50s, although due to the nature of the roads (mostly fantastic twisties) most of it is high rev 30-60mph stuff. Cant understand it myself as Im near the limiter much more than usual on those routes.
Ive gone into the 30s stuck in really bad traffic, but other than that its been superb.
