If I was in your position, there would be no choice. I'd have to get a car. Here, the bus service should be every 10 minutes and it should take 25 minutes to get into the city centre. Should being the operative word. But, in the grand scheme of public transport, the service here is quite good and it's just not quite bad enough to warrant getting a car.

I am thinking of getting a scooter though, if I could find somewhere to park it and guarantee it wouldn't get stolen.
