[H] Rocket League Items [W] Moto Racer 4 - Key

Hi ! I've got Moto Racer 4 (free).
I don't have Rocket League, but a friend of mine does, and of course he would be interested by a key.

But since Moto Racer is a free key, I don't feel it's legit for me to trade that game for a RL key which is not free :/ You can add me anytime to discuss.
