I'm not familiar with the term "people carrier", sorry. Is this like a minivan?
If so, many minivans are ~similar in size, weight, and capacity to modern SUVs (not all SUVs are a Chevy Suburban :-)). For example, you can compare the Honda Odyssey to the Mazda CX9 and the specs are actually not too different:
Mazda CX9: weight: 4,409lbs, 199″ L x 78″ W x 68″ H
Honda Odyssey: 4,482lbs, 205″ L x 79″ W x 70″ H
