The long version

Deleting the wing costs you the parking-lot recognition a GT3 usually trades on, so ordering a Touring has always self-selected for buyers who wanted the drivetrain more than the audience — the manual take rate backs that up. Allocation mania still pulled some flippers into the pool early, which is why values spiked hard right after launch before settling back down as the frenzy passed. What's left skews toward people who actually wanted a 9,000 rpm engine without the wing's commentary, and they use it exactly the way Porsche built it to be used.
