I have found another used M3 for sale at the BMW dealer:
2009 E90 M3, 2000 miles, S. Gray w/FR, DCT, USB/IPOD, Parking Sensors, 18" wheels priced at 60K. No sunroof and no packages. Is this a good deal? I live in a small town were E90 M3s are rare. The dealer prices (new and used) are very firm due to supply and demand.
