I actually prefer my E92 only having 2 rear seats as they are larger and more befitting a sports coupe.
But I too have a family and the E92 alone would simply not suffice - happily my wife fancied the E91 and so we have one of those pending delivery to cater for the whole family, including Nandi our Labrador!
