What would I be missing out on if I bought a used GT 25th anniversary?

We just got our first PS (PS5 slim with disc) since the PS2, where I cut my teeth on GT4.

If I bought a used 25th anniversary GT I assume the PS4 codes as well as the PS5 credit and 3 car pack codes would be used/missing. But, what about the soundtrack, avatars and Special Toyota GR Yaris? Would I get those, or are those all 1 time use codes for original buyer as well?

TIA!

If my memory serves me correctly, those are all single-use codes.
