The Desperado is mainly based on the Chevrolet El Camino, with inspiration from the GMC Caballero.
The First Generation, manufactured from 1958-1960, is mainly based off the 1960 El Camino, with cluster taillights. The performance is somewhat sluggish, as the car is heavy, and the top speed is 120 MPH. Road handling is okay, but it doesn't corner well. Offroad handling is moderate to excellent, and load hauling is respectable. Crash deformation is below average however, and it can take 3 frontal hits before failing.
Generation Two, manufactured from 1963-1967, is based off the '66 Camino, with the grille of a 1980 Ford Fairmont, and it shares design cues with the 1970 Chevrolet Monte Carlo. The performance is more perky than the First Generation, but not by much. Handling is more stable, with improved handling, even though it may still fishtail. The improved top speed is 135 MPH, and offroad handling and load hauling is the same. Crash deformation is average, and it can take 5 hits before failing.
The Third Generation, manufactured from 1968-1972, is based off the 1972 El Camino, and it retains the front turning signals from the Second Gen, but with slightly thinner headlights. The taillights are inspired by the 1977 Chevrolet Chevette, but share the location on the bumper used by the Camino. The performance has been evened out, and top speed is 151 MPH. The handling is more comparable to a muscle car this time, with improved offroad handling and cornering, but lesser load hauling. Crash deformation is average again, and it can take 4-5 hits.
Gen Four, manufactured from 1973 to 1977, is based off the 1975 Chevrolet El Camino, with some design cues from the GMC Caballero. The performance is has been slowed from the previous generation, because the car is larger. Top speed is now 136 MPH, with handling comparable to Generation Two, along with load hauling, but it is slightly more stable. Crash deformation is okay, with 3-4 hits before failing.
The final generation, manufactured from 1978-1987, is based off the 1982 El Camino, with the bed of a 1978 Camino. The performance has been perked up once again, though it's still not comparable to the third gen. Top speed is 139 MPH, with handling that's cushioney, and cornering may not always be reliable. Offroad handling has been downgraded this time, with bumps being very noticeable, and load handling being improved, though. Crash deformation is not that impressive, with only being able to take 3 hits before failing.
SS: In the Third and Fourth generations, a slightly improved handling version, the SS, is available. The cosmetic differences are an 'SS' in the grille, and in various other places on the body. Performance wise, the engine is slightly bigger, and the handling is more stable. Top speed is now an impresive 170 MPH.
Classic: In Generation Four only, a 'Classic' version was offered. The performance differences are a larger engine, but the suspension stayed the same..giving it a top speed of around 150. Cosmetically, the car has rectangular headlights, and bars on the bed standard.
