Car choice (what type of diesel or even a petrol?) SORRY!

[leemarkadams]

Hello all, will soon be looking to change my everyday car (BMW E46 330D Sport) for something newer as it had nearly done 200K miles (but still going strong!).

Anyway, am thinking of the following:

BMW 330/335D
BMW 530/535D
Merc C220/C320 CDI

Now I do about 18K miles a year so what are peoples thoughts? I want something that will be 'economical-ish' and still be a little bit sporty for when I want to actually enjoy the car and cost no more than £15K. Or should I say sod it and get a petrol?

Thanks (and sorry in advance).
