When they do the G1 and Peterbilt Prime they will be mine.
I know some people don't like non transforming characters but the Jada die cast vehicles I've got so far are really nice and will look great next to robot modes of the actual Transformers figures.

The hard part will be tracking these down.
I had to go to Japan to find the Western Star Prime and Barricade as the releases seem to be quite limited. I wish they'd bring them to Australia but given how empty I find shelves here I won't hold my breath.
