I think your statement about people talking more often about the bad things was right on point. People rarely talk about the fresh pot of coffee in the waiting room or the free car wash with service or the lifetime free oil changes. All of these things are true in my experience.
A lot of what you see was the startup problems DC faced with the introduction of this car. Most of that is behind them now. There will still be the odd problem that some dealers will be less than quick to handle. I even had an early problem with the free 800 help number but I would bet that has also been addressed.
So buy the car and get ready to smile until your face hurts.
