Looking at the list, it seems clear to me they are using some undoubtedly complicated formula to establish eligibility at the $80k level.
I suspect variables likely include things like passenger capacity, drivetrain configuration, ground clearance, towing capacity, cargo capacity, etc etc, and you have to check some number of the possible boxes to qualify.
Stabbing in the dark I’d guess the 7 seat MY qualifies as a “van” due to passenger capacity but the 5 seat MY variants and MME are somehow missing the mark for “SUV” for reasons TBD.
