A good friend of mine has one for like 3-4 years, she is very satisfied, plus she looks rather unique in the streets, because you do not see many of them. But all other friends of mine (esopecially men, well certainly!) tell this is not a car. My driving instructor told me that if I would use that "cut-off" thing to study to drive, I'll never be able to use a normal car.
I find them cute otherwise, but would not buy one for me. Stll, if you think about amount of petrol it uses and parking space needed for it, it starts to bve really attractive.
