Hi there. I hope you can help. I need to be able to transport 3 adults and 2 children in car seats on a fairly regular basis ( so myself, kids and grandparents)and am hoping to not buy a big seven seater. So my question is which car has the widest back row seats? I need to fit a very bulky cybex sirona and a high back booster ( probably maxi cosi rodi air protect) in the back and squeeze a slim adult in between for short to medium journeys. Is this even possible or should I just go back to looking at mpv's? Your experiences and thoughts would be appreciated!
