Believe it or not, it is useful even if you live close to the coast. During certain times of the year, there is a lot of marine-related humidity in early mornings and the windshield is really fogged up. Heated windshield comes in very handy (a moot point if you have ordered HUD). Same goes for heated steering wheel and heated rear seats. Once you get to live here, even 50 degrees feel like it is 30 back in the East Coast.California w/ a cold weather package?
