Really. It is not a visual hack for sure right? Not to mention that the Mazda MX5 is NOT a boost car. It comes as an extra if you buy the biggest boost package so even if you have boost hack, you cannot purchase it.
You can do this video even with my car changer, just like anybody else.
How about making a video where you add that boost to your account with your hack, then go into the game and buy all the cars? That would be a bit more convincing than changing a string in your browser from 0 to 800.000.
