Thanks for the quick response.

The transmission bugs me...even if the
car is at operating temp, the first couple
of shifts are hard (doesn't shift until
3500 RPM). I don't have another C220
to compare this too..my intuition says
can't be normal.

I have the LCD type of climate control and
I'd don't see any C<->F switch at all. I'd
love to switch it without taking it back
to the dealer.

I'll try the alarm test.

BTW- I understand this car has a dust filter,
any idea how to access it?

Thank again,
Chandra
