I got the lowdown on my VIN (5D80L4Z500496), but how about production numbers? How many Sprints made that year? And I imagine white was pretty common.

74 Sprints 4,783 were made. Accoring to Dan Carr.

Per the "Standard Catalog of Chevelle 1964-1987" by John Gunnell there were 4,873 Sprints sold in 74. Interesting....

OK OK so i made a typo! 4,873 is correct...

Hmmm, that's pretty rare. No wonder my mechanic's ears perked up when I told him it was a Sprint and not an El Camino. I've also got the split sliding rear window. I hardly ever see that on El Camino's, let alone Sprints.
