reminds me of the story I heard in 1980’s , I checked and it would seem to be true
"incidentally I have a cute story about Rootes for you. Rootes Melbourne was a British company, remember, and Chrysler Australia bought them and it was known as Chrysler Rootes Melbourne plant. And in Australia you did not have a new model every year, so they had VC, VA, and VB, didn’t call the ’78 and ’79 because you didn’t have a new model every year, it was a letter designation. And they had VC and the next model was VE. We didn’t have a VD model. Because someone says “to root” in Australia is intercourse and someone said, “I don’t think we should introduce a model VD. I can see the headline right now: ‘Chrysler Rootes Melbourne introduces VD into Australia.’”
So we went from VC to VE."
and root is a four letter word here in aussie
