Don't laugh, the Ford GT has ventilated seats that both heat and cool.

 

Gee, my pants have a ventilated seat...........wondr what that's about

 

I guess the people down south would laugh when we tell them about our big electric cord we use to plug in the engine heater during the winter. The back of the HHR is just the right size for the cord reel. Got to stop each 3 miles and plug it into a new outlet.
