To be honest, having your own car (OK, between 2 or 3 of you) is great as you share costs, and if you're prudent you can pick up a cheap deal and not lose too much money, and in some cases make money when you sell ! Sometimes a group of cadets will buy 2 cars between them, and sometimes an individual cadet will buy a car to themselves, it depends on your budget but it's not too much of a headache; plenty of cheap rust buckets about
Petrol isn't as expensive as the UK, tax and a w.o.f (MOT) is relatively cheap unless your car is broken, and insurance is very cheap compared to the UK.
