Octavia v Ceed v Civic V Leon

I'm after a super economic car - 2013 or 14 model with no more than 15000 on the clock. Any opinions? I'd want integrated sat nav, cruise control and decent audio but economy the main driver. Needs to be diesel. I do >30,000 miles a year. Needs £0 road tax. Octavia (Elegance) the favourite at present as most bang per buck.

I like the look of Leons, but don't know anything about them.
All in all the best car I ever had pleasure to drive as a reps car.
Road - Wilier Izoard Centaur/Cube Agree C62 Disc
Allround - Cotic Solaris
where do you live and where do you windsurf and can I have a lift?
Edit is this you?
