This was the first summer that I left the D200 in the car all summer (South Texas sun even kills full-sun rated plant life you can buy at the plant store). No damage to the $75 camera, not detectable anyway. I did leave the spare battery in its charger and it would discharge 30% / month. Moved it to the plastic protector it came with.Do either of you worry about heat hurting the car cameras?
Pictures are fine even when the camera itself is at 100 deg F. I keep everything in a backpack that is on the back passenger floorboard also shielded from direct sun.
