I'd love to see more pictures of this rare truck! Everybody knows El Caminos, but say GMC Caballero or Sprint and they just look at you funny...

I worked at a Pontiac/GMC dealer back in 1980, and put the Diablo graphics and stripe package on several Caballeros - and a couple of regular pickups as well! One black Caballero got the full Trans Am Special Edition graphics treatment as well, right down to the wheels and a LeMans nose!
