Cadillac CT5-V Blackwing
Why 5.5: The last supercharged V8 super-sedan with a clutch pedal, and buyers know it — manual take rate near half, collector hedging already visible in the flip data.

Sound
The supercharged 6.2 LT4 bellows through quad pipes with real bass and audible blower whine, and the active valves are not faking anything. But 6,600 rpm and forced induction mean no top-end crescendo. Above the F-Type because less of it is switched-on theatre.

The long version
GM knew this was probably the last stand for the supercharged LT4 wearing a manual transmission, and buyers who cross-shopped it against an M5 or an E63 and picked the Cadillac anyway tend to take the three-pedal choice seriously rather than as a checkbox. That seriousness shows up in a take rate for stick shifts unusually high for a modern four-door this powerful. But 'last of its kind' framing at launch pulled in a hedging minority who bought one to park rather than drive, and that instinct is what shows up as softer flip resistance even with take rates this healthy.
