Most of the readers here are probably old enough to have watched the original G1 Transformers from the eighties, one of the best of the series. After a few seasons, the successful cartoon later became an animated movie that broke the hearts of many children due to many characters being killed off, I won't spoil it but you should check out the original Transformers G1 Movie, it's rather depressing.

Transformers was originally a Japanese toyline, made into an animated show by the Americans, despite this, many of the characters seen in G1 still transform into Japanese cars, such as Ironhide, a Toyota Hiace, and Inferno, a Mitsubishi Fuso Firetruck. And yes! These are licensed vehicles, many of them are.
One of my personal favourite is an Autobot named Sunstreaker, who transformed into a bright yellow customized Lamborghini Countach. Sunstreaker was one of three Autobots that transformed into Coutachs, but his is the most unique version with a much bigger engine at the back.

I believe this is a Series 2 Countach
Judging by the early wheel design
