Pulled the trigger. SA is a very good friend of mine and he's a BMW mechanic. Just quoted me this for 2010 e92 m3:
Alpine White w/ Fox Red w/ CF trim
Cold Weather Pack
19" forged wheels
rear parking sensor
ipod & usb adapter
plus destination & gas guzzler tax the MSRP was $70650. Gave me 3k off so around $67000. Looking at CARS.com it seems like Invoice price is around $65500. I guess 2k over invoice for 2010 is not bad???
