Hey!
I've just graduated from university here at Portsmouth and have had my car for the whole three years, and if I could give you one piece of advice it would be to not take your car. Honestly, unless you physically need to (which I did) it is not worth the hassle. I can't even explain how much of a hindrance it has been the past three years having my car here.
For two years I had to park down a dodgy alley as it was the only place I could find which didn't have parking restrictions close by, and I am surprised it was never stolen or broken into. Plus, there's petrol costs, insurance, maintenance, and you probably won't even need it. I don't know what university you are going to but most places have good transport and many places are very walkable.
A lot of students bring their car when they move into private accommodation as there will usually be parking, but more problems can arise then. For example, we have parking restrictions on our road so unless I change my vehicle registration to here, I can't get a parking permit so have to park elsewhere. It's honestly all a bit of a nightmare really...
Hope this helps a bit, and if you have any specific questions I'd love to help a bit more!
