On my 2nd shelf I decided to use my vintage toy service station with 2nd story parking and added a couple of HO scale buildings to create this diorama. It also came with plastic cars mostly European with a few American cars. The detail is only fair since it was made for kids. Their scale is less than 1/64. I mixed it with some HO models as they seem much closer to this size. For a more detail info about the service station
I have some HO like that, some EKO brand?
