The model was switched to a Renault wagon, which was smaller but priced the same, plus an additional 21% tax. There was only one automatic car available on-site, no choice given. Either you accept it, or you have no car. Unlike our previous self-driving trips in France and New Zealand where there were upgrade options. So what's the point of booking in advance? It seems the same as not booking at all! We didn't get the model we reserved. Under normal circumstances, a free upgrade should be given, but they just shrugged and said there were no cars available, take it or leave it. We had no choice but to accept it!
