Same here with my '19. Personally, I feel the sales numbers will not be what Ford expects, and when they do a poll as to why, the resounding answer will be, "that hideous (or any synonym) dash, of course!".
If I did entertain getting an s650 (unlikely because of the dash), it would have to a black one, which lessens the big, open front grill and makes the rear end, where the lights are, more cohesive.
Along with a sensor that dings you in case someone accidently leaves the tablet in Starbucks and drives all the way home without it. That would be bad ... lol.
It is great that you are stoked and I hope you enjoy your yote. Yes, the Mustang is not a Pagani... it has much more history, heritage and pedigree, and should be treated as such.
The rear crease is ok and it is growing on me. The black around the lights needs to go away, however, or keep it and add black between the lights like the s550. Go one way or the other IMO.
