I clicked on this thread half-expecting it to be by Eddie, and something completely different.
Check your local Kohl's this time of year, or other places that sell yearly exclusive Christmas ornaments... They often have quirky stuff that would fit in the 1:18 scale. They had a badass grill a few years ago that I passed up on but wish I'd gotten.
They also had this ornament:

Or something similar, but I can't recall if it was exactly 1:18 or smaller.
This really deserves its own thread!
It is really difficult to judge which ornament would be 1/18th just by the pictures.
I know these are:

Which grill?I got that grill(from ebay for like $5), it's awesome!

I don't think they have any good ones this year.
