I would look into some of the trans issues with the M6. My cousin has owned two different 2011s and both had a problem with getting into 2nd gear. But even more annoying is the three failed oil pumps before the car hit 50k, the last ended up grenading the engine which GM would have fixed but for his computer tune.

Also, we ended up swapping out the parts that are different to upgrade to the 2012+ suspension with GM parts.
