Cheers so far guys, will defo be looking at some Ford product - focus and fiesta depending on what I can find locally. Fiesta ST probably overkill, maybe just a Zetec S? Older Focus diesel? I don't know if they are any good.
Doogy, yep, my GF has a panda 4x4, but I think she'll let me use that If it gets really bad for a week or two. 4x4 is probably too much of a drag on the fuel otherwise.
Stan, shame the Micra is one of the worst looking cars on the road, given Nissans current leftfield styling direction, surely its due for a re-vamp? 1.5dCi Juke might be good in a few years time though eh...
