Again some great comments and perspective - thank you.
I'm seeing the same asinine and dangerous driving practices by people texting or clumsily using their cell phones. It's really scary how people wander all over the road, crossing the center line sometimes.
I have resolved to equip my future Challenger with front and rear cameras. My cousin did this years ago to his Miata and recorded someone rear ending him while stopped at a red light. Can anyone say social media and the Fear Of Missing Out (FOMA) psychological sense that leads to not being able to lay the phone down and get back to it at a safe time is a plague. I'm raising my hand here.
The 10% rule of thumb for depreciation was new information for me.
Bottom line, as everyone has said, is buy the car you really feel you want.
For deano379 and others who have commented on HP...I'm abandoned the thought of tracking the car I buy. I will enjoy the posts vicariously of those who do! So my car will be a Sunday fair weather local driver. What is it about having more horsepower - the jump from 385 to 485 and in your case up to 700 plus HP - that makes driving the car more fun? Is it the sense that there is just so much more in reserve? The quicker, smoother acceleration up to the speed limit. I hear this from video reviewers too.
For me the jump from 420hp (Turbo) to 485hp (Scat Pack) was a bit of a toss up though maybe the Scat Pack was kind of the winner, so to speak. The Turbo weighed in at around 3400lbs vs. 4000lbs+ for the Scat Pack but the A8 in the Scat Pack shifted lots quicker than the manual in the Turbo.
The jump from 485hp to 707hp when moving from the Scat Pack to the Hellcat was really eye opening.
Now I have to add that when exhibiting the proper restraint the difference in acceleration between various cars from my recent experience: 217hp Boxster, 420hp Turbo, 485hp Scat Pack, 228hp JCW, and 707hp Hellcat; is they are about the same. They are the same because my right foot sees to this.
But those times when conditions permit and I can use more throttle the speed at which the Hellcat gains speed is amazing. In a video of a guy driving a Hellcat he got on the car and of course it did what Hellcat's do. A big grin appeared on his face as the car accelerated. After a bit he lifted and chuckled and commented "That's never going to get old."
And he's right.
Given various circumstances where I live and drive I drive with the proper caution given how traffic is, how the law frowns on any exhibition of speed (if only they frowned upon other infractions by the same amount driving would be lots better here), but once in a while for a bit of time I can unleash more of the Hellcat's 707hp and my reaction is the same. A big grin and a chuckle and the feeling is that never gets old. It is as good this time as it was the first time.
Dash cam: I have a Thinkware F800 dash cam in my Hellcat. I didn't get the rear camera setup but a co-worker has it in his Mini and he swears by it. The front camera is very nice. I may one of these days when I have the time get the rear view camera installed in the car.
I have a 2nd camera to install my my JCW when I get around to it. For this install I might let a shop install the camera along with the rear view camera. The camera can be connected to battery power directly so the camera is "on" (active at any rate) all the time and can detect vandalism, hit and run, or just record who or what was around the vehicle while one is away. The camera can be configured to switch off if battery power gets too low to prevent the camera killing the battery.
