Developer Psyonix will be introducing new very rare and rare customisation items to their “Item Attribute System” in Rocket League's next update. Among the new items are some new rare car decals and some very rare new boost trails.
The new trade-in system, coming later this month, will allow players trade up to five duplicate uncommon or rare items at a time in exchange for one rare item. You can see an example of this trade in system in action in the screenshot below.
Once the update has been released, the new trade-in system can be accessed under the “Manage Inventory” option in the garage sub-menu. Furthermore, Psyonix have revealed that they plan to implement a player to player trading system in a future update.
