Chevelle, El Camino, or Monte Carlo?
I suppose I'm as guilty as many others when I have sections for Chevelles, El Caminos, and Monte Carlos where applicable. However, that being said, it's my assertion that an El Camino is a Chevelle and a Monte Carlo is a Chevelle - just a different body styles with their own style numbers (57 and 80).
Many tend to think an El Camino is something different or special. In some ways I suppose they are - I tend to think of them as something special. Hence, I've created separate pages for various things such as trim tags, warranty Protect-O-Plate cards, and photo gallery. Other sections such as paint, interior, production numbers, etc. the El Camino is included with other Chevelles. The same for the Monte Carlo from 1970 through 1972, where applicable some Monte Carlo information (such as interior codes) are listed separately from other Chevelles.
El Caminos and Monte Carlos were not built at all the final assembly plants as other Chevelles were but El Caminos were offered from 1964 through 1972 and Monte Carlos from 1970 through 1972. El Caminos were offered in the same trim level as the 300 Chevelle (5380/5480) and Malibu Chevelle (5580/5680) in 1964, 300 Deluxe Chevelle (13380/13480) and Malibu (13580/13680) series from 1965 through 1969, base Chevelle (13380/13480) and Malibu (13580/13680) from 1970 through 1972 with a one-year only series of SS396 (13880) in 1968. Monte Carlos were offered in only one body style, a 2-door sport coupe, body style number 57.
The Monte Carlo is, in my opinion, just another series and body style of a Chevelle. In 1970 and 1971 the Monte Carlo shared the same overall series (13000) as other Chevelles but had its own body style number, number 57; in 1972 the Monte Carlo shared its series designation (H) with the Concours Estate station wagon but many of the same parts that went into a typical Chevelle went into a Monte Carlo and the Monte Carlo was built on the same assembly line with other Chevelles at those plants that assembled the Monte Carlo.
