But if im use addon cars i can find them driving around or only spawn them? Im just starting and I do not know exactly how it works.

there you go: 2012 Lamborghini Aventador LP700-4

Hello.
Im just download 2012 Lamborghini Aventador LP700-4 and replaced it. The car spawns only in white and green colors and if i trying repaint in LSC i cant do that, is it any way to have normal paint colors. Can anyone explain to me what to do?
Thanks for any help.
