The mission you’re probably thinking of is Old School Hits in GTA Online. It’s a newer featured mission series, and the black old-school cars clue fits the kind of mobster-style setup people describe around it.

Why this is the likely one

  • It involves a crime-fam, gangster-style vibe rather than a classic heist setup.
  • The “offices” part sounds like one of the mission interiors or briefing locations tied to the current GTA Online content.
  • The “old black cars” detail matches the sort of gang vehicles players commonly notice in these missions, though that part can vary depending on the exact job or variant.

Another possibility

  • The Bureau Raid is a GTA V story mission with an office-heavy setting, but it’s not GTA Online and not the best match for your PS5 Online description.
  • If you meant a contact mission or another Online job, the exact name may be from the current update’s mission list rather than the older base-game missions.

Fast way to narrow it down

Tell me one of these and I can pin it down:

  • Was it from a CEO office , agency , or casino?
  • Were you fighting Italian-mob style NPCs or FIB/agents?
  • Was the mission from the main map , a phone call, or a mission marker inside a building?

TL;DR: Most likely Old School Hits , but if you remember the building type, I can identify the exact mission name more confidently.
