Spaceship Toy - Late 80s

I'm looking for a toy from late 80's. It was a spaceship with a double nose like the Millenium Falcon, but not with a rounded body, was elongated. The ship can be opened ahead, and there was a lot of little vehicles like micro machines in different colours. Maybe had a size of 12 or 14 inch (30-40 cm). Maybe it was from a Japanese or Chinese staff, I don't know. The colour of the spaceship maybe was grey (I can't remember so well) Thanks a lot!
