The 4 seater design changed again around 2006 which is the same design as the current model where the rear is longer and the hood is different so the hood can be raised without having to tip the seats forward
So to recap
Pre 1997 - bench rear seats, no headrests as standard so hood can be raised
1997-1998 no 4 seaters made
1999 - new design as the video with Chris Goffey where the hood can only be raised with just tipping the seats forward a bit because the frames are right to the back of the seats
2006 - new design with new easy(ier) up hood and longer rear where the hood will go up without tipping the seats forward but from what I can remember on the hire cars I've had, I think the rear headrests have to be removed ( might be wrong on that)
