This video from bandxi claims to show a solo car duplication glitch for GTA Online that supposedly works after a recent patch. The cover suggests a straightforward method for duplicating vehicles quickly.
As with any duplication glitch, Rockstar patches these frequently. What works today may be gone tomorrow. The title explicitly states it's a glitch, not a legitimate game feature. Using duplication glitches carries a real risk of a temporary ban or a full account wipe, especially if you sell too many duplicated cars too quickly.
I can't confirm the specific steps or if this method still works. Glitches are often patched within days. Before you spend time on this, check the video's comments and upload date to see if other players report it as still active. If it looks too easy, assume the risk is real.
