I just cruised up the largest hill on I-75 near here with the a/c on full and the temp got to right under 100 dC (in the black 300D). There was always some space between the needle and the 100 dC mark.
It was 100 dF outside and with the a/c on inside the car was probably 75-80 dF. At least the sweat evaporated pretty fast
