Unless one requires turns. Factory? Is that why they can send it to the dealer as is? Bottom line the demon has a drag suspension and the 500 has a track suspension. I take a Viper or 500 all day over a demon! I’m assuming he’s saying above 100mph it’s not close on track. Which it’s not. Has the S run consistently faster than 10.5/6? If not they are damn close when comparing best 1/4 mile runs.
