For what to have a second generation? The Chrysler 200, or some Fiat vehicle? I'm not a fan of the Fiat 500, and isn't that basically the only vehicle Fiat has? That and the Panda, which is a slightly better car then the 500.
they also have the fiat 500L, like a Mini countryman, which to me is nice for what it is. i had one as a rental when my car was at the body shop because of an accident I didn't case. I liked it.
I just don't think that it is a different version of the 500. They should have named it something different to make it its own thing. This is probably because because I just don't like the 500 at all so I have a pretty strong bias.
Tell that to Fiat. That's how their naming structure currently is, they have other vehicles with '500' followed by a letter, but I agree that it's not the best way to go about naming a series of vehicles.
