The long version

Buy one new and you're mostly paying for the badge and the valet reaction; buy one used, after the steep early depreciation that built the Bargain Window reputation, and you're paying enthusiast money for an AMG-sourced V8 and a chassis road testers keep calling genuinely sorted. That splits the ownership pool by purchase timing more than personality — original owners chasing theatre already moved on to whatever's newest, while secondhand buyers arriving now skew toward people who actually researched what's under the badge. The cars that get driven properly tend to be the second- or third-owner examples, not the first.
