If it is of any help, my is300H is described as an "excutive edition cvt" and it does have folding rear seats. Bear in mind the parcel shelf is rigid and the clearance from boot floor is not huge but golf clubs are fine, as are skis.
And in the front seat it does feel a little cramped - snug ? - and that feeling persists after 5 years. But the seats are very comfortable. The car is quite low and perhaps that contributes to the closed in feeling. In fact next to my daughter's huge Nissan it is like a racing car!
