Trunk Air Conditioner Vent

I drive a Town Car. Yeah, I'm lucky!  But one thing I have wished it came equipped with is a trunk air conditioning vent, possibly with an on off lever for those hot days down here in the south when shopping, especially for groceries. A vent to cool off the trunk a bit would come in very handy, as it can be some distance from the super markets and shopping areas to home in rural areas!

You'll never get me to switch vehicles.  It's a Town Car or nothing, as far as I am concerned, and this is the only way I can even think of making it a better vehicle than it already is.
