I can in Rocket League Den Orange Fennec. Not swapping with a friend, why?

Hi

I wanted to give my Fennec (Orange) to a friend today but I can't swap it does anyone know why?

I play on xbox and so do my boyfriend

So I can soon swap everything except for the Fennec in orange

You should always be able to swap Fennec, restart the game or log into the account again!

Did you buy Fennec in the shop? If so, you can't trade it because items that you bought in the shop can't be traded with other players.

Where did you get the Fennec from?

Yes, thank you
