Totally agree with your assessment. I'm comparing my M4 to my previous 335i(Dinan stage 2), and 996 911. Massive torque, and a great (although different) sound. Mine is "too" loud at cold start and quiets down after about a minute.
Toys & comfort were the "something extra" I couldn't do without. And now I'm spoiled when I drive other cars. The (P)ark being missing is ridiculous. On an incline it holds but level in my garage it wants to roll.
I can't stand the warning every time I go to shutdown.
I do not have the guts to tear into those rear tires yet (I'm at 8 weeks and 1,500 miles). Good on you!
Lastly I agree with their survey issues. If they want real feedback then they need to fix the process. You are a customer that is willing to spend time giving them valuable feedback to help them improve- and its pushed to the side because it will penalize the dealer.
Keep the videos coming. Thanks for spending all of the time and energy on this.
