I have a few more days before my MS order is locked in and the only lingering question on my mind is whether to stick with the 85D or go to the P85D. I have only test driven the former. However, the only reasons I can discern for getting a P85D are: You want to race it on a track against other fast cars Having just the 85D would leave you with P-ness issues You like making youtube videos But really there is no practical reason... right? My lease payment goes from $1034/mon up to $1380 for a P85D and to $1554 for the P90D. 50% more money to go from a 0-60 time of 4.2 down to 2.8 secs. And yet I'm still thinking about it! Gah!!
