Pros:We had initially rented a manual Fiat 500 but when we got to the rental desk, the Hertz employee gave us a brand-new (18 kms on the odometer), semi-automatic, fully-loaded (leather seats, navigation), Fiat 500S. We had signed up for the most basic and cheapest car and we ended up with a pretty decent one in the same class, and there was no added cost to us. The unlimited kms were very good for us as we did about 1850 kms of driving over the 8-day rental period. Pick-up and drop-off were quick and easy. The entire experience was enjoyable.
Cons:My only issue, and this has nothing to do with Hertz, is how weak the engine of the Fiat 500 was. We had quite a bit of trouble keeping up with the European traffic on the highway. Driving on the very hilly landscape of Spain made some parts of the highway near impossible to climb without losing much speed. Other than that, it was a very enjoyable rental.
