I disagree. The real value of the Hellcat series of vehicles is the factory warranty on the 707HP feature. That's 30k miles of 1/4 mile launches and smokey burnouts backed by the factory. The Chargers, Challengers, and GC's are generally pretty low quality compared to an M5, M6, or X5/6M. The inside of the HC is approximately the same quality as my Laramie PW, which is to say not all that great. A $55k HC is a hell of a value considering it comes with a $30K engine and transmission. For $85k+ I can buy a GT350 with 3L whipple ( or Corvette/Camaro with a Pro Charger) and make the HC look stupid (no warranty though). The upper price tiers of the HC/TH lack real value. I also don't see the value of the Demon outside of the collectors resale and warranty either.
Perhaps I'm jaded but 700hp isn't impressive anymore, that's junkyard LS and Ebay turbo territory.
