Hire car companies in France

I thought you were driving from Paris TO Nice. Are you going the other way?

As long as your rental will be for at least 3 days, I suggest you go to the AutoEurope or Kemwel sites and compare their offerings. We've used several of the companies they do business with and never had a bad experience in France. I go for the lowest price for the type of car I want.

Unless you hire from a guy in the back of a garage, I can't imagine there would be any DISREPUTABLE companies if you've heard of them.
