These are plastic cast cars that are made for the architectural model industry. The stated scale is 1/300th scale but work just fine for 1/285th scale (6mm) use.
I've been using these myself for some time now and you've probably seen them in photos of many 1/285th scale buildings and parking lots on this site. Several people have written me and asked where to get them so I figured I'd make them available on the site. I buy them in bulk from China and repackage them in packs of 10 for you.
