Rocket League is resurrecting two classic cars from a former game in their June update. Psyonix announced today that the Marauder and Aftershock Battle Cars will be added to the game. The cars come from the developers 2008 game Supersonic Acrobatic Rocket-Powered Battle-Cars which is a precursor to Rocket League.
You should be able to pick them up if you get the anniversary edition of the game releasing June 24th. If you opt out of that you'll be able to pick them up for about 2 bucks each in mid July on their own.
