I've considered buying one myself. I've rode in both the automatic and the 6 speed version. The 6 speeds aren't geared right for the car in my opinion and it was disappointing to me to be honest. I've got a 525 HP first gen Camaro with a 4 speed and 3.73 gears and it honestly feels faster than the M6 hellcat. Dodge took the trans and rear diff gearing from the viper which weighs 1,000 lbs less and is targeted at road coarse type racing. If the 6 speed car had the scat pack's gearing, it would be much more fun to drive to me and would prompt me to pick it over a 6 speed scat pack. 1st gear in a HC tops out at 63 mph, your running 95ish in 2nd, and 3rd is well over 100. For a 707 HP car, it seemed like it took way too long for it to wind up and was ready for to the next gear. The automatic car however, that was insane to ride in and this is coming from a die hard 6 speed guy. Just the way it accelerated, it felt like it had 300 more horsepower and this was a stock auto HC vs a stock M6 HC. The ZF 8 speed makes the hellcat a true performer. I think with what I know now, I'll likely purchase a scat pack as the acceleration to 100 mph 6 speed car to 6 speed car isn't much different at all when you factor in the better gearing of the scat pack vs the 200 extra HP of the hellcat. The hellcat's power really starts to shine at 100+ mph and pulls on the scat pack then and I don't do that too often so it's not really worth it for me personally. Maybe this will help you in your decision making process.
