We've been driving 4Runners since 03 with our 96 and the last two with our 04. In 03 we had our first daughter. 2 years after our second daughter came around. Now at 5 and 7 years old we've gone through a lot of stages, from strollers, baby seats, diaper bags, grocery shopping trips, 14 hour drives to Vancouver etc etc. to now just booster seats. With the 4 of us on board and all our gear (depending on what we're doing at the time) and we've never been in the position where we thought we'd like more room or couldn't make things work.
We deal with a fairly long winter in my area so the winter capabilities were a big shopping item for us when we originally though 4Runner. Now there's no way we'd go anywhere different for our family hauler. My wife never drove winters before we got the 04, now she won't drive anything else.
