You are correct and I was wrong. After digging a bit I found out that C230 was indeed sold in the States, unlike "lesser" models like mine (C200). Strangely enough, I lived in the same state where you seem to reside for over 15 years and never ever saw one...not in NY or NJ either.
I might have seen them in SoCal. Maybe they were only sold there? I could've sworn I saw one in SEPA but we do get a few California transplants here.
