I was thinking I had heated mirrors, but, recent weather has proven to me they are not. Bummer. The first car I had with heated mirrors (91 Dodge Daytona), I thought "What a dumb thing! Who the hell needs heated mirrors" ... but they actually helped quite a bit with fog, ice, snow...

Then I got a car with an auto dimming rear view mirror (93 T-Bird), and I thought "What a dumb thing! Who can't manage to flip the day/night switch on the freakin' mirror?" ... but after driving that, then switching to a car without it, I missed it.
