The dash mounted rear view mirror is a great gadget IMHO. The mirror eliminated an annoying blind spot that I still have with modern cars. Something I remember from my Dad's 55 New Yorker that I believe the 55-56 Imperials also had is a wonderful outside door handle. A push of the thumb would bring the handle into your hand . Kind of subtle ,but made a big impression on me as an eight year old . This is probably not Imperial exclusive, but the southwind gas heat would rate high on my gadget list. Especially living here in Minnesota!. Clay Smith 67 Crown Coupe 60 Custom > > >
