We are shopping for a new car, going from our current mid size sedan to a small or mid size SUV. Currently have one LO but plan on two. Hoping to have this car for a long time.

I'm currently trying to decide how much I care about seating people other than our immediate family- most of the as we are looking at will fit two adults and two car seats, maybe squeeze a small adult in between. But then you pretty much can never drive anyone else around? Some of the cars have a third row that folds down- so usually it's trunk space but can seat more people (like a Toyota highlander or Acura mdx). Is that really helpful? Or does it not really matter? I kind if want to keep it as small as possible while meeting all our needs.

Eta: we don't drive a ton and will only have one car for a while. Live in the city for now.
