I have the same search criteria as you, though I also want a MT and the M Sport package.
I have assumed there are few 2011s in the system as they're still too new for their leases to be up. FWIW, there are lots of 2010s.
I'm not completely clear on when the N55 entered production with the E92s. Was it a running change in the 2010 MY or did it start with 2011?
But I agree with everyone else, at least drive it and if you like it buy it
