No-one can give you a definitive answer because they aren't you, they don't know where you'll be staying, they don't know that you'll end up in a relationship with someone who lives 2 tram rides, a bus ride and a 20 minute walk away, or that you'll spend one weekend a month cursing public transport trying to get home, they don't know that you're timing belt it due in 6 months and it'll fail it's MOT with about a grands worth of work.
Oh and neither do you
What I do know is that leaving a car sat unused for 4 years will not do it any favours, it'll also see another 4 years of depreciation (may not be much of an issue depending on what you drive). You can also forget about your now claims in 4 years you'll be starting from scratch.
Either way knowing as much as we do from your post i'd take it down and then if it wasn't practical i'd get rid. Just make sure you don't leave anything on show and have a steering lock (new students are prime targets for theft).
