My sister and I were big fans of Jem and the Holograms when we were little.We didn't have this car, but we did have the Star Stage:
You could put some of the dolls on the pegs (they had little holes in their feet if I remember right) and there was tape player so you could play the tapes that came with the dolls. It's all explained here in this commercial.
We watched the cartoon, we had some of the dolls and lots of the clothes, and I even wrote out the lyrics to some my favorite songs. You see kids, back before the interwebs brought us lyrics websites, we had to get lyrics using the listen, pause, write, listen, pause, write method.
