Depends on how often and where you use a car. If I were to travel often because of my job I'd say rent it. If you mainly stay in one place or if the places you need to go are comfortably accessible by car, get your own car.
Despite the fact that I don't even have a drivers license I go with personal car (mainly because I don't really travel in my job).
