I too, recently had 2013 35 as a loaner for 10 days. My comparison between mine and new one is this. Mine is 4.8 with AD, active steering, multi contour, and 20". Loaner w/o these options. I was surprised as to the ride and handling, it is big different, it is not like typical BMW, the steering feels numb, not as responsive compare to mine, ride is bumpy, seats not as comfy, the gas paddle is slower respond from stop, once it is going i feel plenty of power. I lost interest of driving this thing in 10 days, can't imagine owning it for 3 years.
