I traded in my 2011 Z E92 MR for a 2013 XK-R in polar white. If you want HP, Torque, Classy Interior (deep blue leather w/ tan stitching), Aston Martin look - since designed by Ian Callum, go with the Jag XKR or XKRS. One thing I miss about the M3, tight handling; that's it. Other than that, I love the Jag. The exhaust is unreal. Is you haven't test driven one... it would be hard to get real feedback from a M3 forum. Good luck!
