I seem to be managing between 30 and 32, but I do more motorway than town. Having said that I am having a bit of fun occasionally, so I daresay I could get a bit more once the initial excitement has worn off...
...if it ever does!
I have been told cruise control is not very fuel efficient, but I've been using it for most journeys. Even trundling along at 30 in fifth I flick it on, and its perfectly happy. Its the first car I've owned that will actually accelerate in fifth from 30!!
