Has anyone rented or purchased a vehicle in spain, i was thinking of just buying a little moped/ 50cc motorcycle to move around since im going to be there for 6 weeks. Anyone have any ideas about this? Purchasing or renting?

I rented a scooter in Spain while I was there for about 3 weeks. It was quite easy really, I just went in and rented one...I did bring a local with me just to make sure I got a good price.

How much did it cost? Do i need to have some sort of license?

TO be honest I don't remember how much it cost, as it has been a few years. I just used my US drivers liscence and had no problem.
