Ah yes, the most obvious reason for low production numbers in '58 overlooked, slow sales! Nice work squeeze. I'm sure that is correct because there was a recession in '58, so certainly folks did not want to spend so much more just for the Cameo's snappy looks, especially when the handsome Fleetside cost only slightly more than the common step-side, and the El Camino was also available at pretty much the car price point. I think it must be a combination of all these factors that led to the Cameo's demise. Either way, with only 1405 produced, there aren't many running around anymore.
