Parking made easy with elevator (set 6394)

This set is called "Metro Park & Service Tower" and is actually two sets coupled: a gas station and the parking lot are built on two different baseplates. The car parks are on level 1 and 2, accessible via an elevator, while the car wash is on the ground level. The other building has a gas station and tools for repair.
