Heinz I love the Galaxy - had a scare with mine a while back when I had a gearbox problem and immediatley started looking for one the same.
I currently have all 3 kids in the middle row, youngest in the middle - I can reach him from the drivers seat which is useful.
I can actually get in the car and stand in from of the children when i'm strapping them in - even when i'm this pregnant!
My plan when the baby is born is to put the oldest child in the 3rd row seat - easiest to reach that carseat for strapping in - put buggy next to her. Put baby next to me in the front and have dc 2 and 3 on the middle row with a seat for dp when he's in the car with me. Obviously dd1 can go in the middle row when dp is not going to be in the car but actually she loves sitting in the "boot".
The good thing about it is that all of the seats can be removed in any combination, all the seats fold down and flip mostly out of the way if you need them too, they all recline like front seats and slide backwards and forwards. So it makes fitting carseats in them quite easy. Mine has a lap belt in the middle seat but there are several seats by Britax that will fit on a lap belt. Even with all the seats in you can still fit in a cosatto duet lite in the boot space, but they cannot be pushed one handed.
The only negative I can find with my car is the fuel consumption - but the diesels are much better than the petrols which is what i've got
If you are looking at one check that the windows all work properly, that the central locking does lock all the doors, and that the key for the ignition is the same as the doors - if its been broken into through the drivers door you end up with a different key. Also check all the keys will start the car because they have to be coded in if not and probably pay about £50.00 and its hassle
If you are using a Phil & Teds is should have plenty of roomn in the space where seat 7 goes.
