This video from UnhookingV2 promises an easy solo car duplication glitch for GTA Online on PS5 and Xbox, specifically calling it a "nightclub dupe" or "mansion dupe." The snippet mentions it works after a patch, which is a strong hint that this is an exploit rather than a legitimate game feature.
As with any duplication glitch, Rockstar patches these frequently. The method shown in the video may already be fixed by the time you watch this. Even if it works, using duplication glitches carries a real risk of a temporary ban or a full account wipe, especially if you sell too many duped cars too quickly. Rockstar tracks suspicious activity.
Do not attempt this on your main account if you value your progress. Before you spend any time on this, check the video's comments and upload date to see if other players are reporting it as patched. The title and snippet alone cannot confirm the method is still active or safe.
