Do it over and over, and you can replace all your cars with the more expensive one. You can find these duplicated cars in your garage with instructions from the video.
Tip 1: The car that you want to duplicate has to be fresh and should not be a previously duplicated car. We recommend that players purchase a new car to perform this money glitch.
Tip 2: Players must keep in mind that when you sell cars, you get more money based on the modifications you have made on the cars. So make sure that the car that you intend to duplicate is not only new, but has some expensive modifications too.
Players who use duplicated stock cars will make very little money when they try to sell them at Los Santos Customs.
