The only way I'm getting this car is if I can find a carseat that will fit in the back seat comfortably. We have a Britax Chaperone, but it's pretty big, and doesn't fit. I'm hoping to check out the B-Safe and I'm thinking it's a little smaller and might fit better.
We just had a baby this past June and fitting a car seat and stroller in the car was a requirement when looking for a new car in August (I was specifically looking for an SUV, but the dealership had a CT200h in stock and they were selling like hot cakes). We were able to fit a Graco car seat (bundled with the travel system) in the backseat with no problems. The seat in front of the car seat only required minimal adjustment (a couple inches) for it to fit securely and comfortably for the baby car seat. I found it more convenient to put the car seat on the rear passenger, so I could have comfortable room for driving and ease of access to my baby just by reaching over. Here are a few videos of my baby in the car seat: Videos Link
