I was looking at them pretty seriously a couple months ago. Test drove a '15 automatic the same day as a '15 charger (was looking at scat pack, but they only had an r/t RT). World of difference in the chassis, visibility, ergonomics, etc. Handling and ride are incredible. I thought driving it was actually more fun than the cts-V I drove, though those weren't on the same day. The only downsides are styling, mpg, and the auto transmission isnt nearly as good as the ZF 8 speed. MPG is poor, but probably not far from where you're at. I was surprised how much I could feel the difference in weight from the charger.
I was still seriously considering one but found out I'm going to Europe for a year.
