NosherN – I had the comfort seats in both a 5 Series and a 7 Series (in fact the 750i Sport that I owned had them in the rear as well ?) and the range of adjustment is amazing. I particularly liked how the backrests are ‘split’, so you can bring the upper section towards you without pushing your lower back forwards. I would say that although they are described as ‘comfort’ seats, which implies soft, they are actually closer to the sport seats. Another thing I liked was the fact that the side bolsters automatically ‘relaxed’ outwards when you parked and then hugged you back in to the seat when you started the car, which eased access and egress. On the X5, you also now have the benefit of the standard adjustable suspension, so we were thinking if we got one that we would lower the car to the lowest setting to get in and out. Helpfully, the car automatically resets to the normal position once you pull away.
