I've actually bought more HW cars in the last couple of weeks than Star Wars toys.
I picked up a couple BttF DeLorians and then the regular DeLorian for my buddy. And I also snagged a Batmobile which I think is the same, maybe a color difference, as the mystery Batmobile from a couple years ago.
I didn't know that HW did an Ecto-1. How long ago was that? I'll have to look for a photo of it, sounds cool.
Edit -> Just looked it up, that's pretty cool!
