If GM wanted me, as a former Camaro and Firebird owner, to consider buying a Camaro in 2010 and 2018, when I bought my Challengers, this is what it needed:
1. Not to look like a Hot Wheels car.
2. Have a useful trunk.
3. Have a little more head room.
4. Make the greenhouse a little bigger (That would kill most of the "Hot Wheels" complaint, and the head room issues.)
And if they really wanted me to consider it, make it look like a '70-'74 Z-28 and I'm there. They messed up making a tribute to the first gen car, and then in 2016 doubled down on the ugly. Looks alone kept me away, but the other issues ended any chance of me buying one. The continued good sales of the Challenger have proven they nailed it pretty well.
