Simple, post any link and explanation of your favorite mod for GTA series. I'll start it off with speedometer mod for Gta sa. Its really fun and I think it has gasoline. http://www.gtainside.com/en/sanandreas/mods/18897-speedometer-gasoline/
LCPDFR. Turns the vigilante mode in IV into legitimate policing. I can't stand car mods btw. I hate seeing real cars mixed with fictional ones.
