20. 1975 Ramblin' Wrecker
Funny story behind this one: When model car designer Larry Wood created this tow truck, he originally included his home phone number on the side of it. So, when it was first released, children from all over the country called his house. He eventually had the phone number blacked out from the side of the truck when it was reissued a few years later, but not before he fielded thousands of calls from curious kids.
