In 1978, in the Japanese market, the B121 model replaced the B120, with the most notable change being a switch to a plastic grille of the type used by the B110 coupé. Also notable was a change to upscale round instrumentation. The B120 was particularly successful in South Africa, where it was known as a bakkie. In 1977, for instance, it was the most sold commercial vehicle of any type there. It continued in production there long into the 21st century. It received a very mild facelift in 1978, with a new grille and taillight treatment, as well as interior upgrades.
