None of the pictures I can find show any designated charging spot. The charger is at the entrance to the dealership, next to the Kunden parking spaces. If you want to reach any space but the first Kunden space you will need a long cable to go all the way around the first car.
All pictures always show cars parked on unmarked spaces, and there's definitely space to park on the other side of the charger where nothing is painted. There's still a lot of space to drive by. Based on the same pictures, this area appears to be used to showcase cars, so it might not be available to plug in either.
