Overwatch question

I sold my original copy of NFS Rivals for PS4 after I finished the game.  To clean up space on my PS4's hard drive, I deleted my save file as well for the game.  When I had the game orginally, I got to Level 50 in Overwatch, and ulocked all the Overwatch cars.  I would really like to pick the game back up again.  When I do, will I still have all the Overwatch vehicles I unlocked in my garage after signing into the EA servers?  Will I have to play the Overwatch challenges again from scratch?
