Can't access tabs or find purchased DLC car

Hi. I’ve been playing this game for a short while. Just unlocked Autumn if that gives you an idea of how far along I am. I saw a ZR1 as a dlc car and bought and installed it. I can’t figure out where it is. Ive restarted the game and one s console many times. Oddly, I cannot access any tabs in the menu. I can only access Home and Creative Hub tabs. Can’t access Horizon Life, Fortune Island, Team Adventure, Cars, Rivals, Clubs or Marketplace. They are greyed out. Is access to my tabs and car something that has to be earned? Its a bit confusing. Thanks

Edit… after playing another race, the aforementioned unlocked and I was able to eventually find my vette. Damn that thing is fast!!

Sounds like you havent played far enough into the game to unlock those things
You unlock them at level 20
