Thanks for the comments, Neon & Gag Halfrunt.

I was surprised to not see so many original Fiat 500/600 actually. Even the 90's cinquecento. But lots of 90's seicento, and the latest 500.

I wondered if these busses were electric or gas-powered, as they were not completely silent like the Prius when it runs on battery for example.

What is the model of the red Fiat taxi ? I forgot to check the badge on it, and I did not make a photo of the rear.
