Hi XB0XL1ZARD - we don’t have any updates on specific models or brands until we announce their addition to the game, but you can see a brief explanation of the various reasons why cars aren’t included at a given time in the Car Voting Guidance thread in the Suggestions Hub.
There are over 4000 models users have expressed interest in seeing added to the game. If you’d like to see the 2012 Challenger added, be sure to vote to express your interest: Dodge Challenger 2008-2014
