Ok, how about this spot  -   
Near and behind a front turn signal.
There's  big cavity in there, it's not especially heated by anything, and
it's easy to get to.

Yes..that's the whole problem. I'm trying to mount it someplace where
there's no direct sunlight, no UV accumulation, no engine heat, no headlight
heat, no heater hose heat, and yet outside to measure ambient temps. On top
of that, someplace where I won't knock it off on a stump or a rock, and
someplace where it isn't getting winter rain and snow full blast. Dumb
little problem, but there it is. On Saabs the OEM sensor mounts conveniently
above the driver side air dam, but we don't have any real place like that.
