Hi, I currently have an e34 525i Touring, and it's too narrow for three kiddie seats in the rear. How would this set up work out in a 740i (not iL)???? Specifically one rear facing infant seat, a forward facing toddler seat, and a child booster seat. I really, really, really don't want a mini-van or a truck!

Also, beyond simple fit (yes or no), does anyone have experience with this set up? How "pleasant" is it for trips?
