OP - shame you didn't post up a couple of months ago - traded in my Jerez Black E90 M3 DCT, high spec, 12 months old with less than 8k on the clock.
I think with the E90 M3 now ended production prices may start to firm up soon. Good luck with your search.
2011 AW E90 M3 DCT - Current
2010 JZB E90 M3 DCT - Sold
2009 6MT E90 LCI 335i M -Sport - Sold
