I tried finding this information on the various appraisal websites but could not find any information for used 2012 models. Only new pricing seems to be available at this time. Does anyone have an idea of how much I can expect to get for trade or resale on a 2012 E92 M3? The car has less than 5K miles and is pretty much immaculate. Options include ZPP, Black Novillo Leather, DCT, EPS, Sat Radio, BMW Apps, and Heated Seats. Wheels are 18" 219M. I know that pricing varies across markets, but generally, in terms of percentage of original MSRP, how much can I expect to get on trade/resale? Hopefully what I am asking makes sense. Your help is greatly appreciated!
