If you are over 26 then maybe....at least in the UK if you are younger than 26 you have to pay a MASSIVE young driver surcharge(a car can cost 30 pounds/day to rent, but a young driver surcharge can be 100 pounds/day). It's literally cheaper to lease, a brand new Citroen C1 will cost you 100 pounds/month + ~80/month in insurance. The car is new so whatever goes wrong with it you are covered, you just have to put petrol in it.
