408 Beaumont Custom convertibles with V8 power for '67, plus an even 100 base Beaumont V8 convertibles, plus 66 SD396 convertibles. I don't have the 6-cylinder production, but not many built. Throw in winter driving in the rust belt and a bunch of decades, the rare sightings make sense.
My twin brother and I scrapped several "A-bodies" two decades ago (that were way too far gone)...even poor parts cars, some having rotted frames that one could not even tow (down the road) - we did scrap a "plain Jane" 6cyl. BEAU conv. / Ontario roads, had lots of winter road salt...rust cancer was real bad, without oil spray undercoating (my vehicles got it every fall, from the mid 1970's).
I parted out several rotted out Chevelle/Beaumont's back then and saved all the good stuff, by packing parts around a one owner 1965 Chevelle S/S, dry stored since 1980.
(I later purchased the '65 hardtop, 10 years ago.)
- stored stuff on the dry top floor of a rented barn, parts 4 feet deep and 4 feet high around 3 sides of an original '65 hardtop
Now you got me thinking, but I believe our junked base Beau convertible, did not yield much.
It was one of the worst "swiss cheeze" rust buckets I ever saw...probably parked on grass, for many years.
- total Chevelle production was approx. 33x more vehicles, compared to the Beaumont...in the years they were made (comparing apples 2 apples)
- even the 1966 S/S Chevelle production of one model option, equaled approx. all the Beaumont's ever made, in 6 model years (from 1964-1969...2 & 4 door, wagons & conv.) in all body styles
Baron - good luck on your next Beaumont find...takes time, these cars are extremely rare today.
