This casting of a VW Microbus is released by Tomica in Japan. It features an opening side door and an impressive level of detail. Because of its Japanese origins, the steering wheel is on the right.
This 1977 release is red with a white roof and door. I found this example buried in the bottom of a rummage sale box. The top sill of the door had broken, but I was able to repair it with super glue.
