University towns usually have very good transport links, so unless you're disabled / have a job in an odd location / are in some tiny rural university, then there should be no need for one. Certainly - as I have a bike - I feel no need for one in my uni town, and the only reason I need a bike is that I have a tendency to go outside student areas at times when public transport isn't running.
Tell your dad that there's no way that you will be able to afford a car on a student budget (most likely true), so he will have to fund it for you. I'm sure that will soon concentrate his mind.
