Lou,
I remember talking to Mr. Crook about this and he said it was one of the
reasons he thought that the Bristol didn't need A/C as there was a
tremendous amount of fresh air available from the dash vents and the foot
well vents. Not sure if he had sampled the summer heat in the Southern
States! I do however find the heating and ventilation system in the
412
better than most modern cars, as long as the rear window vents are open (or
the top off!)
