After 1990 the series was slightly improved as quality level, like RABA engines, RABA transmission, plastic seats (or sometimes with vinyl upholstery cushions - mainly coach versions, but also some urban versions), and many models were taller.

Some of them, were even fitted with fluorescent lighting, but in very few cases, this retrofitting was mainly made at the host garage.

Târgu Jiu's last Rocar DAC trolleybuses, which had operated since the network was opened in 1995, were finally withdrawn from service in December 2021, after new Solaris Trollinos arrived to replace them.

It was also exported, only as trolleybus version, in Bulgaria (used in Varna, Burgas, Sofia) and Ukraine (Kyiv, Kharkiv, Dnipro), however they were modified and fitted locally with other motors and controllers than in its mother country.

Also sent as test vehicles in former Yugoslavia, Czechoslovakia and Hungary, but were not accepted (probably mainly due to the fact that these countries were also having their bus manufacturers - IKARBUS, Škoda and Ikarus respectively).
