yeah.. thats kinda dumb...but if you want, go for it...
personally I start the car and roll the windows down and go. I can take that 10 seconds of heat, and that thing isn't gonna keep your car from warming up, it may help a little.

 

yeah i'd rather roll down the windows and save that money for gas. It seems like it would help a little but not enough to be worth the money

 

I really couldnt see how that fan would work. Really all your doing is blowing around hot air. Plus, I seriously doubt the fan speed would be sufficient enough. Lastly, look at the other ads that site is trying to sell, cheap. Now I also own a Mazda Millenia and it has a solar powered trunk vent that is similar that works so-so.
