FH4 limited content

I've started playing FH4 on the xbox and currently I'm lvl 68. I can't seem to find a way how to purchase car packs (says exclusive content and cannot be purchased), can't access forzathon events, no Fortune Island no LEGO Champions, can't tune cars (ony download others), can't join the eliminator as it says only for xbox gold membership, and the forza playlist is all expired and can't play it. Is there any way to get this content? Without this it seem that there's not much to play on the map anymore, only replaying the same races. And i can't see anyone online drive live on the map. How do I meet with the other random people in FH4?
