Consider what your family needs to be comfortable.
"How you define comfort is individual, but everyone needs to fit comfortably, first and foremost," said Teresa. But physical space doesn't necessarily guarantee comfort. If you're a family who spends a lot of time in the car together, consider what your kids will need to be comfortable beyond there being enough space.
A few things to ask yourself as you shop: Will all of your children's car seats and boosters fit in the back seat of the car? Is there enough additional room for shopping bags or luggage when everyone is riding in it? If your kids are prone to backseat brawls, can you keep them far enough apart to avoid World War III? Are features like seat warmers, air conditioning vents, and cup holders things you want in the back for the kiddos?
