For this year's Halloween-themed build, I went with the Packard from The Addams Family TV series. It started as Monogram's Packard Phaeton, and while a couple of details aren't quite right - I found out too late that the TV car had a longer wheelbase and a black interior - it was a good kit and enjoyable build. The wheels and hood ornament are 3D printed items I drew up, Thing's box was scratch built from balsa and craft sticks, and the horn is a modified Hallmark ornament. A full write-up of the build is available here, and as always comments/criticisms are welcome!
