Why go for the petrol model if your going be concerned about mpg? I am assuming you are concerned about it... nearing 60 mpg in my diesel 1.6 titanium and it is only increasing as I commute 12-13miles one way to work.
1.6 tdci, remapped to 120 bhp, Panther Black Titanium with rear view camera, nav pac and front sensors. Always willing to stop & help in any situation I can. Karma is a beautiful thing.
