Our family tradition during road trips is playing a game called slug bug. Each time a person spots a Volkswagen beetle, we say "slug bug" enthusiastically. My youngster in the back actually keeps score in the back seat and somehow always manages to win.
I haven't see a gold one, but I'm keeping my eyes out for one like this.
Essentially, you are thinking of converting a tiny slug bug into a MONSTER bug! That is awesome. Sometimes bigger is actually better.
I grew up with “ bugs “, they run forever and parts were always cheep. Air cooled no hoses...... not much heat in the winter. Everyone had a “ bug “ 😀
