Everything was fine with receiving and handing over the car.
The only thing that could be "fixed" a bit - we had problems with locking and unlocking the car, as well as opening the trunk. We even changed the key battery 2 times but it didn't help.
After a couple of days, when contacting the owner, he suggested how to solve this problem. It would have been nice if he had informed and warned us about this from the beginning.
But overall a positive experience.
