I picked up a CPO 2012 Z4 35i last week. It only had 4,000 miles on it! It has the M-Sport package and is a 6MT (long live the manual transmission!).
I am super excited about it, and so far love the car! This will be my daily driver for my roughly 100 mile/day commute to and from work.
(sorry for the crappy cell phone pic as this was on my way home from picking it up)
