I am way out of my league here, but somewhere I heard that the interior heat on
a car is affected most by the amount of glass in the car. Something about "long
rays" and "short rays". The heat passes through the glass and the rays are
altered and then cannot pass back out????????
My MG seems to stay cooler with the top up, this may substantiate the above
info.
