There are already a ton of glitches on Grand Theft Auto Online, and one of the newest ones to be uncovered lets you make millions in less than an hour, but you will need a million to get the job done. This glitch, revealed by YouTube user Caspahz below, lets you duplicate exotic cars that you already own so you can sell them for quick cash.
In order to exploit this GTA V glitch, you'll need to start an invite-only game online and invite a single friend to join you.
Once you're in the game, both of you will need head over to your garage where your friend will need to stay for the entirety of the glitch. Once you're at your garage, make sure that it's full with cars, and then proceed to order and purchase a Z-type car from Legendary Motorsports, which will cost you $950,000.
Since your garage is full, it will ask you to replace one of the cars. Select any car and you'l then respawn somewhere else in the GTA world. Make your way back into the garage, where you will find that your friend is missing and the Z-type you just purchased will have replaced one of your cars.
At this point, have your friend invite you back into the old game that you were both in. This will respawn you in the garage again, except that your friend will reappear and all of your cars will be duplicated and stacked on top of each other.
Take them over to Los Santos Custom and slang them, while your friend stays in the garage. Repeat this process, as well as blowing up cement mixers, until you're rich as fuck.
