I thought long and hard about this before voting Hot Rod. The poll was specifically asking about favourite Autobot Cars from childhood, and while I had an Autobot who turned into a car (Flash) I didn't have an Autobot Car as a kid. But when I turned 18 and started collecting Transformers properly, one of my first acquisitions was a reissue "Rodimus Major" i.e. Hot Rod. I do have a bit of nostalgia attached to that toy, and while I'll always prefer TFs with a bit more articulation, I also have fond memories. Plus, 18 was long enough ago now for me to say that was "when I was a kid". So I'm going to have to go with Hot Rod. I also bought a Jazz reissue, but it wasn't as good as Hot Rod.
