Funny you should mention this, we tried it the other day. You're never gonna believe it, but with my hatch we got 18 people in! We fit 10 in the back (very, VERY uncomfortably, they were stacked sardine style

), then 8 in the front. 2 in the drivers seat, 5 in the passenger seat, and one sprawled across. I got the car started, but we couldn't move, on account of I couldn't move the shift knob.
Wow, it sounds so unreal... 18 people in a 240... Oh yeah, we left the trunk open too, so it's kinda cheating, but oh well. We would'a had some broken legs on our hands (pun?) if didn't.
