Hopefully I'm posting in the right forum, I can't seem to find any actual Santa Fe Sport forums. I know there IS a difference between Sport and regular Santa Fe.
I've seen 2 web reviews that state that the 2017 Santa Fe Sport can have the front passenger seat fold flat. But I can't find an owner's manual and Hyundai's website is sparse to say the least when it comes to details (almost as bad as Ford).
I did test drive one, but the sales guy didn't know.
