Trying to decide between two model years and styles of MS, besides the 30 extra miles, new nose, and center console if I was buying a CPO 2015 90D with Subzero Winter package, Smart Air Suspension and Ultra High fidelity what would the other differences be with a 2016.5 MS 90D would be? Beside the nearly $11,000.00 and year younger and extra year of battery warranty. Searching the internet is giving me no joy in finding this answer. Thank you.
