i was cleaning my car the other day and realized i never really payed any attention to my vin plate and took a look. and noticed that on it nowhere does it say ef but mine says ed. so i guess to get on about my question.

why is it we in the states call it an ef if it is in fact an ed?

maybe this is a dumb question and maybe it has been answered somewhere on here before but i havent read it so thought id ask.
