Hah, I just bought the car! - I wasn't intending to commute at first but changed my mind. I'll might even end up getting a flat in a few months.
It's only 3 times a week and a 160 mile round trip. Based on 30mpg it works out at just over £400 per month.
I'm in 4th year, so I've lived and enjoyed the campus lifestyle. I save on having to pay rent for a student flat and I don't drink. - that's how I can afford the fuel.
As for insurance, I just turned 21 so it's only around £700.
