Will you build no claims on that policy? If not then I'd suggest getting a banger and your own policy - long term the only way you'll reduce your premiums is by building no claims.
Honda Civic is a good shout.
The 1.6 Sport civic is quite a tidy little thing for your sort of money, it wont hit your economy targets but nothing much will. They're relatively keen feeling for a small petrol engine and at least look the part.
I wouldn't personally bother with the diesel, it's a very rough and ready unit and not particularly well suited to town driving. I doubt it would give you the sort of issues more modern diesel units would with your sort of driving but honda make nice little petrol engines, it'd be a shame to forgo that for the isuzu sourced diesel option.
