The only way you can mod it right now is to get Horizon Diamond and do it yourself. However modding cars on your account will only be unicorn cars (Nothing special) and the Civilian cars which I don't wanna say you will be banned for them but as long as you only use them in single player you will be fine. Oh! and you can buy things from the storefront you know like 1,000 here and there but don't go buying $50,000 paint jobs right away. If you want PM me and Ill give you my GT and Ill gift you some cars. AS FAR AS MODDING CREDITS! Dont mod to 999,999,999. Just like 80mil. and I promise you, you will NEVER run out.
