We have a Camry, and it fits three, though the Radian only works with our middle seat belt for some reason. I've had a lot of trouble installing the Radian in different positions in both our cars. I would say try the carseats you'll be using in the car before buying the car. It's really the only way to make sure, especially since even if the seat is wide enough to accomodate three, some seatbelts don't work well with certain car seats. Good luck.
