If they are all front facing then buy whichever truck you like. I've leased an 05 QC and an 08 QC and they were great for my little guys. If they're still on the young side the quad is convenient because you don't have to reach too far back for snacks, drinks, blowing a nose, etc... Having said that, now that Chrysler isn't leasing anymore and I had to BUY one, I voted for the CC for the extra interior space. Either way, if your kids are more than 3 feet tall they'll find a way to kick your seatbacks!
