Buying a car before UniWatch
Deffo find out what the details of any uni parking policy/permit are, as they can be v sneaky/downright obstructive. The permit for mine costs about £100 per calendar year and takes a few months to process.... you can see the problem there. It's as if they are in someway obligated to provide the facility, but really don't want to.
Have you looked at supermarkets near your accommodation, sometimes they can be useful for that if there’s not a bus stop close. Maybe look at the cost of a car usage compared to public transport
I would 100% have regretted not having my car with me. It helped with my course (photojournalism) and we had so many adventures around South Wales because I had a car.
