How often are you going to drive it?
Might be cheaper to rent a later model a couple of times per year.
It's not going to cost you much as you clearly don't plan to use it.
Just make sure it's in decent condition with good brakes, tyres, working audio and a smooth gearchange.
And probably some other bits I missed that someone else will point out shortly...
Pre 2011 cars need to be serviced every 6 months/6,000 miles. You can get away with doing it yearly with that mileage but it may be harder to sell the car later. Post 2011, Nissan switched it to a yearly/12,000 miles service schedule.
