PJ, I live in Plano Tx and have had my HAH since January. So far the interior temperature stays comfortable whether it be freezing or hot as "_ _ll". I keep it in "auto" mode all the time. I also have tinted windows as do most of us that live in north Texas. Also, it has been posted that in stop and go traffic, the auto stop will go off if after so many stops, you do not accelerate over 11 miles per hour. I have only experienced this once.
I really love my car, but it is disappointing to spend the extra money for a hybrid and no one has noticed since there is no distinctive color and just a small "spoiler" to distinguish it from other accords. I have only been asked about my car by one person who did 'stalk' me down when I was in Austin.
My boyfriend is purchasing a Highlander Hybrid. It is even harder to tell it apart from the non hybrid version. Looking forward to comparing the HH performance against my HAH. We should get it the first week of August.
