im digging the dlc, so far I have all of them. the war pack, renegade, made man, vegas, greaser and jimmy's vendetta. I also found a mod that will alow free ride and 3rd tune up option.
So far this is one of my top 5 games. Still have a few wanted posters to find on the story mode before I get all achievements for the story mode. And a crap load of stuff to do on vendetta.
