An additional real world comment about the new C which probably applies to many of the new generation MB's.

I am so accustomed to the absolute simplicity and convenience of most all of my previous MB's locking system. You lock the drivers door and everything locks, more importantly, you unlock the car and everything unlocks. I don't know how many times I have grabbed the trunk or a non drivers door to find it locked. I have to fish out the key and press a button to get it unlocked.

I am going to see if this is a programmable feature, I don't believe it is.

Just one of those small idiosynchrosies that is inconvenient and against all keenly developed MB habits. What makes it worse for me is that I constantly switch back and forth between the C and my 300E.
