Hey guys. Im curious as to how i change a normal Sultan RS to a cop car almost like the FBI car. Can it be done? One of my friends did it with his comet.

yes, get openiv, double click on your saulten rs and click fragment, see what fires it needs get the files, get zodler, find a tut, look on forums on how to.

You'd need Zmodeler 2 and a basic familiarity with it. It wouldn't be a difficult job, perhaps another modder could do it for you if they are free. All it would really involve would be extracting the Sultan RS and perhaps the FBI Buffalo from the game, importing both into zModeler, removing the lights from the FBI car and placing them onto the Sultan, delete what's left of the Buffalo and then export.
