I spent a summer in Texas where my car would hit 185F if parked in the sun during the day. Light tan Corolla with tinted rear windows, so not even near optimal in terms of retaining heat. I baked cookies on the dash one day. Not hot enough for caramelization though so the flavor was lacking. Surely I had covered parking most of the time.
