Back in those days, the salesmen used to tell me you don't need air con because the car has a sunroof and I always used to think what an unusual view that was.
Um. Whatever demented soul who ordered the truck I now own specified "sunroof." Nice glass panel, electrically operated.
It leaks when it rains, and it's a freakin' solar cooker on bright days. I've seen 160F on the thermometer I put under the dash. I finally cut a big piece of carboard and wedged it into the bezel around the sunroof, to keep the sun out.
The only sunroof I ever had that was properly done was on one of my 1972 Capris. It was metal. It had only enough rubber gasketing to control wind noise; rather than depending on gaskets to keep water out, it had a ring shaped drip tray and garden hose sized hoses running down the A and C pillars; just like the rain gutters on a house. Worked perfectly. And you could crank it open in light or medium rain and stay dry; over 50mph the blast from the windshield blew rain back before it could fall in. In fact, the low pressure area where the sunroof was would pull air out of the cabin when in motion. And it was quiet when it was open, too.
The Capri lacked vent windows as most modern cars did, but the "fresh air ventilation" would nearly blast your hair back. And, something I always found hilarious, if it was snowing outside, snowflakes would make it into the cowl vent, through the maze of hoses behind the dash, and out the vents, so it would snow in the cabin as well. Can't get much fresher than that.
