i have a 3 month old and my answer is going to be, "it depends." i have a 3" lift and 33" tires on my FJ and before we had our baby, i didn't think it would be difficult at all. we have a Peg Perego system and i have quickly realized that it is one of the heavier systems out there. you have two latch locations for baby seats...behind the driver's seat and behind the passenger's seat. i could not fit the baby seat behind me without sliding my seat forward to an uncomfortable location...therefore, we put the baby seat behind the passenger's seat. if we have another baby anytime soon, we will not be able to use my FJ as family transportation without me sitting in a very uncomfortable position. i also quickly found out that because the front seats don't fold forward enough (more of a slight tilt), with our baby seat, we have to collapse the handle before dropping the seat into the seat base. with the handle up, the seat just won't fit through the space behind the forward-tilted front seat. with my wife's car and sister-in-law's CRV, you can use the handle and drop the seat into the base. personally, i love the FJ and even though the wife complained and tried to get me to sell it throughout her pregnancy to today, i refused to sell it...she is now getting used to it and does not complain as much. with that said, in my opinion, the FJ is not an easy vehicle for baby seats...at least Peg Perego seats. as someone else mentioned, the suicide doors are more of an obstical in certain situations when someone is parked next to you. before you buy, really think about what you want out of the vehicle. i bought my FJ to wheel, so the sacrifice in inconvenience having a baby seat is worth it to me. if this is going to be the only car in your family, i would suggest you look at a more traditional 4-door SUV. if you have another car in the family and you like the FJ for what it is and what for what you expect out of it, then by all means, go ahead and buy one. with my very mild lift and tires, my wife is not able to place the baby seat in the FJ.
