This light-duty pickup truck was identical to the El Camino except for the name, and the chassis for both cars was based on the Chevrolet Chevelle station wagon/4-door sedan wheelbase.

The Sprint shared exterior and interior trims with the Chevelle Malibu and El Camino including cloth and vinyl or all-vinyl bench seats and deep twist carpeting.

The 1971 models featured the Chevelle's twin parking light lenses, dual "high intensity" headlights and horizontally-divided front grille.

Both years featured rear end styling taken from the Chevelle station wagon (and were shared with El Camino).

For 1972, the Sprint was given the updated Chevelle front end styling, retaining the "GMC" and optional engine badges in their 1971 locations.

The Caballero name was previously used as a top trim level on the hardtop Buick Century Station wagon.

GMC also offered special trim packages for the Caballero under other Spanish names: Diablo, Laredo, Amarillo.

As for the car's old nameplate, GM would later revive the Sprint name for a rebadged Suzuki Cultus sold under the Chevrolet banner.

The Caballero and the fifth generation El Camino shared their mechanical parts with the Chevrolet Malibu series, but rode on a 9-inch longer wheelbase.

Other than different nameplates and minor trim variations, it is difficult to distinguish a Caballero from an El Camino at more than 10 paces distance.

Exterior appearance remained largely the same over the truck's nine-year lifespan, with the biggest changes through the years coming mostly in the form of grille design.

Then for 1982, the front end was changed to a full-width grille design housing four headlights and a four-row crosshatch pattern; this persisted through the vehicle's demise in 1987.

The instrument panel originally featured a "strip" style of speedometer, with the needle making a long sweep across a horizontal line of numbers to indicate speed.

The 1987 model year was the end of the line for GM's North American coupe utilities, which included 420 leftover El Caminos and 325 Cabelleros that were reported first sold in 1988.

Like the Caballero and El Camino, Holden's Ute is based on a car platform - in this case the long-running Commodore series.

For the 2008 model year, GM introduced an American version of the Commodore sedan called the Pontiac G8.

Ultimately, the intended show vehicle eventuated as something quite different, in the GMC Denali XT Hybrid Concept, designed by GM Holden upon the Zeta platform, but bearing no resemblance to existing Holden product ... it debuted at the 2008 Chicago Auto Show, but plans for production based upon this unibody concept were subsequently cancelled circa September 2009.
