seriously looking at the petrol due to short runs, hard to get true realistic figures on fuel, sure theres plenty of you guys out there who can advise, thanks in advance to all

The factory figures are fairly accurate but it'll all depend on your driving style/commute. Biggest cost will probably be depreciation though.
