and if so which car seats do you/ could you use? i am looking at buying a mercedes eclass esate or a peugeot 406 estate some of which have handy seats in the boot which you can flip up for extra seats. they face the back window but dd would need a car seat. have emailed britax fit finder but thought i'd ask you all as well if not then what car should i buy? i want three full size seats in the back for three big car seats and the option of extra seats for when i need them (i'm a cm!) have looked at the zafira too but middle back seat doesn't look that big. ideas anyone please
