The SS20 Cervo received a very minor facelift in 1978, consisting mainly of interior upgrades. In June 1982, the rear-engined Cervo was discontinued in favor of a more conventionally laid out replacement, the SS40. In Chile the Cervo was originally only sold with the 970 cc F10A engine; a May 1979 drastic lowering on tariffs on cars of less than 850 cc meant that the 797 cc F8A inline-four became available in that market. The chassis code of this model is SC80. This was sold alongside a better equipped model with the 1 litre F10A as used in the SC100.
