Hello, are now also standing in front of the seemingly insoluble task of finding a vehicle of the premium class, in which 3 children fit reasonably on the back seat, without which it is a bus. Yesterday the R-Class was a small, though quite handsome light view. My wife prefers a bus, but that’s just not a car anymore. Comfort, driving noise, maintenance against a lot of space… Now my special question: Which position do I attach the baby shell to? Yesterday I noticed that it could be better on the outside seats, because then you do not have to lift the baby with or without a shell over each other. However, the belt lock operation is easier if the shell is in the middle, since the middle seat has a rather peculiar cut, which allows the belt locks to be placed accordingly strangely. I would be very pleased with the answers! MfG Friedmar
