Great, even though I didn't get the Mercedes C I booked, they upgraded me to a Volvo V40. It was excellent, very fuel-efficient. I filled up once for 800 km and drove for thousands of kilometers without spending much. The car was new and the built-in GPS was very handy. I recommend renting a car with a GPS to everyone. As for the domestic navigation devices, forget about them. I brought one and never used it, and now I have to deal with returning it.
