hi, as someone who has never owned a 4, could someone tell me please, do the rear seats fold down flat on post 73 4`s, and if so what is length of the area created from the tailgate? Also what is the internal width between the rear wheel arches, and is the boot lip height actually 52cm as suggested by online dimension images? I am asking this because since joining the forum in spring and failing to buy a 4 at auction my circumstances have changed. I am still interested in owning a 4, and am now, at last, in a position to start looking again, but I now own a pair of Labradors, one of which is old, arthritic and needs a ramp to get into my current Kangoo. Thanks Swampy
