This was the nicest car we've ever had as a rental...but I'm guessing we must have gotten an upgrade. We got a Peugeot 3008, an automatic diesel compact SUV, with 360-degree cameras and navigation, and had only reserved an intermediate sized car. It had plenty of power on the Autobahn and handled smoothly at speed.
The garage was really tight, and a bit nerve-wracking to maneuver through. Also, our large suitcase just barely fit (along with a smaller suitcase and a backpack, and another small suitcase in the back seat).
