You keep praising GTA V car customisation. SR is a bit better with that you can modify every vehicle (well, with a mod but still).
What do you mean with "What you mean?" that is, i do not know "what do you mean" so, i can not answer what i/you mean...Hey guys, what do you mean? Is better GTA or SR? I think, both games are really good, but GTA V is better than SR:IV.
