I lived in Phoenix for five years. You leave NOTHING in your car out there if you value it.
I wondered if there was something special about DSLR's and lenses when it came to high temperatures. As a general rule, I don't leave them in a car due to theft concerns, but I will leave my camera bag in the trunk occasionally on a hot day when I'm out and about. But I assume a trunk does not get as hot as the interior of the car, what with the greenhouse effect.
But I've always left various other electronics such as laptops, compact cameras, cell phones, MP3 players, etc. in the interior of cars year round, and I've never noticed any ill effects.
My work car actually has a laptop installed in it, and it's just a normal HP EliteBook, not something rugged like a Panasonic Toughbook. I turn it off when I'm not in the car, and it does not seem to be bothered by the heat buildup when parked during the summer. Of course, I don't live in Phoenix, but it will still get up to the mid 90's in the summer around here (approx 35 C).
