When Ya Gonna Call?

A friend of mine and I have an ongoing arguement over which is the better 80s film, Back to the Future or Ghostbusters. I defend GB and he defends BTTF. So, I thought for a birthday card, I'd combine the movie's two cars, and have a hovering, time-traveling Ecto-mobile!

This has taken up my time so I couldn't do the DeLorean Mk IV.

That'll be soon, though...
