Lupin prominently wears a pink jacket throughout the show. Thus this series is known as the "Pink Jacket" series to fans.
Occasionally, Lupin drove a yellow vehicle that resembled a Jeep. That "Jeep" was a Volkwagen Thing which was discontinued just one year before Lupin III Part III first aired.
This was once the only series in the Lupin III franchise to not receive any (official) Western home video release.
When Yasuo Yamada, who voiced Lupin until his passing in 1995, was asked to do a goodbye message for the final episode, he said, "You're probably going to make more after this, aren't you? I'm not going to tell such lies!"
The second longest running 'Lupin III' series at fifty episodes.
