This video from DooDooPoo claims to show a method to make $1.8 million per car with the Deluxo or Issi in GTA 5 Online. The title suggests a high-value repeatable payout, which is almost certainly a glitch or an exploit of a specific game mechanic. Legitimate car sales in GTA Online do not pay out anywhere near that amount per vehicle.
If this is a money glitch, it will be patched quickly by Rockstar. Attempting to use it carries a real risk of a ban or a character wipe, especially if you do it repeatedly or share the method publicly. Do not follow any steps you see here without first checking the video's upload date and recent comments to confirm the method still works. Glitches are often fixed within days. Always verify the current status before you risk your account.
