I really miss side vent windows
]
If you know or remember what these are, then you're over 40 years of age.
They were great when cruising down the road and you wanted a little bit of ventilation without the full-blown draft of a completely lowered side window. You would just lift up the lever and your triangular side vent window would open up a la 45` angle. You would get a little indirect air blowing around the driver's cockpit.
My son has this neat feature on his 1974 Fiat Spider Convertible.
