Well...I have no back seats, no interior in the back at all. All the sides are all metal, no spare tire, nothing. Just battery in the back, and it was hilarious to watch 2 people try to sit/lay/fall around/flop around on the bare metal while I drive...4 is the most I'll ever do. However, in the 3000GT, I fit 10 people(including me). Me driving, 2 up front, 4 in the backseat, and 3 people sitting either IN the hatch or their legs hanging out the back and sitting...Don't ask...
It was a cruising strip that everybody goes like 10mph down this verrrryy long strip and all the guys in trucks always pick people up so I said, F-this. I don't need a truck.
BTW, all the people were girls except for one guy that was smashed in the backseat somewhere.
*edit* My 3000GT was more crammed up then my Supra...do I win?
