In all honesty, this is one standard feature that came on my 04 that I wouldn't miss.
I have no problem manually dimming the mirror in any of my other cars.
My complaint with the Crossfire's automatic mirror is that it makes it next to impossible to identify the car behind me.
I've noticed the roof top light bar (on the Police car behind me) is practically invisible after dark.
Now I'm not paranoid, (because I never do anything illegal when I'm driving our Crossfire) but I don't like surprises when Leo's are involved.
Another thing I've noticed, I'm the only one who ever complains about this.
