i have had to tote my baby nephew around a couple of times, and there is one good, not great, not easy way to do it. figure out whichever side you want the seat on, i suspect passenger side, and flip down the half of the back seat on the opposite side. slide it over the flipped down seat, and slide it over. now buckling it in isn't easy, and hopefully you have more than one car seat and you don't have to take it out too often. good luck and enjoy the ride
