BEWARE! We used Kayak to reserve a mini car, a SmartCar or similar. When we arrived in France, we had been assigned a mini - an ELECTRIC one. I have no issue with this in theory, but the car had only a 150 km range per charge, and charging would give us 15-20 km per hour of charging! This would never work for our purposes, and there were no charging stations at most of our hotels/gites. The staff could not seem to understand that this wouldn´t work for us, and then charged us four times the original cost to rent a diesel car, because they only had SUVs available. We had no choice, as we needed to get on the road, but when I checked my original rental paperwork, there was nothing to indicate that we would have limited mileage or an electric car. I would never book a rental car through kayak again, and I expect Hertz to compromise on the price of the car if I cannot drive it more than 150 km per day.
