The CC is 5 passengers, the KC is 4. Personally my needs are a weekend work truck, daily commuter, with space for the three remaining kids at home some times.
My 9 and 12 yr olds both love riding in the jump seats around town, but this obviously isn't meant for long trips.
It really comes down to what you need, I don't need another car.
If you are in the car seat or booster seat phase, get a crew cab, the KC is for a second or third vehicle, rarely used by more than 2 people
