We booked an "Economy" car, described as "Open Corsa or Similar". Upon arrival, we were given a Fiat 500, and the Enterprise employee insisted that this is what we had booked. Ultimately, I understand that according to the Enterprise classification a Fiat 500 is somehow in the same category as an Opel Corsa. But we felt severely misled - especially since if we actually wanted to "mini" like the Fiat 500 we would have rented that for less money from another agency.
