Models sent to Constanta are equipped with resistor controller instead of electronic chopper.

Transmission of all 412E is from Autocamioane Brașov, probably because the motor is somehow identical to the Rocar DAC 112/117/212/217 series.

RATB still operates one, #7459, but it was put in storage along with Rocar 812E Trolleybus #7460 due to high maintenance costs.

Inbus was a collaboration firm between Breda and De Simon, being a popular choice for Italian bus companies in the 1980s.
