And every decent one worth mentioning does. The question is relative comfort and how much "stuff" is required. Four 6' adults with one duffel each will fit in a Honda Fit, but it might not be much fun for a 12hr road trip. I had 4 adults, their camping gear and bikes on top of my '96 OBS once, luckily we were only on the road for 3hours.
Hip's point is there's a big difference between the occasional camping trip and a car that sees regular long-haul road trip duty.
