I already have a white Fiat 500, although not a convertible one. I love it. It is such a fab car. DH likes it too, although I don't let him drive it that often, lol!
The pink one is a special edition I think. Only recently out.
I am definitely trading in for a convertible within the next year.
They are not that small. Boot fits in a weekly shop and all my school junk. Can fit two car seats in back easily. DH is 6'1" and can drive it no problem, and 7y DD can be sat behind him on a booster chair with sufficient leg room. But couldn't be the main car I agree.
