I have searched the forum and it seems like two cars seats fit fine in the rear of the stinger but I will have 2 front forward car seats and a backless booster. Within the next few months it will changed to two boosters and one forward facing car seat. Does anyone have this set up? It looks like either way I have to buy seatbelt extenders. I appreciate the help. The lease deals on the stinger are crazy right now so I am looking at leasing one.
