In 1970 my dad brought home a Nova that was almost the same shade as The Dodge/ Plymouth Gun Metal Gray.
It was a great color sedom seen then and now.
Not tgat it matters but I learned how to drive in that car.
230ci six 3 on the tree, manual drum brakes, and stearing am radio heat only car were only options.
P.overty Caps on Steel Wheels.
He added an under dash cassette player that also recorded
As the only add on.
I lived on the same street as the Chevy Dealer and saw all the new cars come in and get test driven or beat to death in the days of covering the windows of the show room with paper.
I hardly saw any gray cars come out the place. So think it is rare on most makes.
