...and so I collected it on Saturday.  Really really nice - slightly firmer ride than the old 5 and thirstier, but I will get used to those I hope.  Loads of room inside - feels bigger and higher up from inside than the outside suggests (like a tardis) and the panoramic sunroof is awesome.  In many ways it's even easier to drive than the 5 - more responsive and the handling is a real surprise - no roll whatsoever.  B
