Well, wouldn't you know it. The very next day after I picked up three new rides for the Halloween Garage, I found another one! This one was found at a local closeout chain called Special Thoughts. Oddly enough, it's also where I found the last two cars of the same make.
As I mentioned when I picked up the last two, this is a great Halloween themed car. How can you go wrong with a coffin on wheels? It's clear this design was influenced by The Munsters car Dragula. Plus it's got skulls on either side of the radiator and a giant bat hood ornament.
I think I'm going to start hunting down more variations of this car even if the color scheme isn't exactly Halloween in nature.
