My friend is trying to pick up an older 2013 - 2014 P85. The prices on the ev-cpo website are low. He said you can get them in the high $60k or low $70k range for a 2013 or 2014. Pretty good depreciation if you ask me in 2-3 years. That's a $30-40k price drop from MSRP. He doesn't care about Autopilot and is willing to take an older rear wheel drive car without it. The only thing he really wants is blind spot detection. Is that option only available in the 2013 - 2014 models? If so, how can he tell if its available?
