It could be almost anything from the tank to the exhaust so, as it's new to you you'd probably be as well to get your faults read. Hopefully that'll point you in the right direction but if you get them listed before they're cleared it'll give you a sort of history of the car then a clean slate for you to go forward from.
If you're going to stick around you might want to put some sort of location into your details. You'd be mightily ****ed off if you find you live round the corner from a helpful fellow owner.
