I have a 2013 s6 and I am trying to get my wife in 14' s8. She has the two kids, one in booster ( 6 yr old ) and 1 yr old in car seat. My wife is 5'8". The S8 we are looking at is NWB. Is there enough room in the car to be comfortable with the kids, it says it is same size as s6, just hard to believe it is the same

Pls give me your thoughts
