We have 2 cars a VR commodorre and a Pajero
If we were to have another kid we'd have to buy something different as we fill the vr at the moment (me, my partner, our 2 kids-2&1 and his son-8)
and the pajero is modified to be too high off the ground to be putting babies in and out of the middle seat (the babies are in a car seat either side in the back and my step son sits in the very back on one of the fold down seats)
Also if we go somewhere as a family i'd rather us not have to drive 2 cars everywhere lol (imagine the fuel costs!)
