You don't mention the year of car you are asking about but I had an 08 4 seater and the answer for those is yes, the hood frame will not clear the headrests if you try and erect the hood without removing them or tilting the seats forward to about 45 degrees. My rear headrests lived in the shed until the day I sold the car! I only bought the 4 seater as I did the road test for Miscellany (back to back with the then new version of the Aero) and liked the extra luggage space, we had a holiday in Sweden planned.
