Nope, GTA 5 has been handled absolutely atrociously DLC wise. Couldn't give a fuck about any of the multiplayer stuff so there's pretty much nothing that's been released so far. GTA 4 handled DLC so much better than 5.
I agree. GTA 5 is such a fantastic game, my favourite game of the last decade I suppose. It's such a shame that there's never been any story/singleplayer DLC, just the multiplayer/online DLC I don't care about. Would have loved to spend some more time with the game.
GTA 4 in comparison was so much worse in my opinion, I didn't even finish the game. But apparently it had fantastic story/singleplayer DLC.
