John,
If you collected Märklin trains, then you could combine your hobbies and make an entire set of these train cars:
Märklin 48296 (HO)
.....and these:
Märklin 48159 (HO)
Märklin made the one with the Ford Model A on the side in 1, HO and Z scales. They are easy to find on the secondary market (eBay, etc) and with several of these lined up in a row, it makes a very impressive train set.....delivering The New Ford cars and parts from the factory.
