Your car reminds me of one that my friends older brother found in a Toronto alley back around 1977. It was a Laurentian 4-door, turquoise & white with black & white interior (really nice shape). His was a 261 3-speed manual. The car was so quiet, all you could hear was a slight fan noise (and of course the transmission whine in the lower gears). We really thought the Pontiac had more class than the Chevy, I mean look at the rear fenders, tail lights and bumper.. Lots of headroom in that thing. I guess people all used to wear hats back in the days of olde.
