I see about 30-32 (pump) on my commute (8.5 miles 50/50 town dual carriageway each way). Longer runs usually get me 40+.
Computer reads about 36.5mpg over the last ~5k miles, ironically enough about bang on the official NEDC economy for the car (try achieving that in a turbo hot hatch!).
I'm with Admiral at the moment (23, 5yrs ncb live in Hove) and they've been fine, however I haven't made any claims with them so couldn't tell you what they are like for that.
Esure and Chris Knott have given me the best quotes for next year's.
