I have a 2006 E55 that currently has 2500 miles on it. It had an msrp of 88,915, with Premium Package, Dynamic Seats... and Lighting Package. The car is black/black. My question is the lastest Ill be able to sell this car for 79,000.00 BAsically, do I need to sell it now to get 79,000 out of it, or when is the latest. Car will be bone stock upon sale, minus flat hood emblem and star diagnostics lowering. Thanks
