Get what you want. I have 11 5.0 MT w/3.73s. Car has 5800 miles on it. I had
the clutch pedal assembly fixed ( sticking at high rpms) at around 2k. It is now in the shop waiting for clutch/flywheel replacement (bolts backed out), but I do not regret for a minute getting the 6M. The only thing I am not happy with is the totally crappy Malibu I am driving, but that is being swapped for something else tomorrow.
Would I be aware that some were having problems without the internet, no. But I am aware, and my dealer has taken care of me satisfactorily as always. Would I buy another one of these cars, YES, in a heartbeat.
Go for it, and don't worry, if something happens the warranty is there for you.
And hopefully if you should have issues, you have a good dealer working for you as I do.
Good luck to you and enjoy the 5.0 regardless of how you shift it....
