Is the Mercedes-Benz C63 AMG Black Series a good investment?

The thesis

The C63 Black Series is the ultimate W204: 510 bhp from the hand-built, naturally aspirated M156 6.2L V8, aggressive aero, stripped interior, and Black Series pedigree. Original list price was ~£125k; recent sales range £68k–£251k, with strong examples now £120k–£180k. Just 800 built globally, and it's the last naturally aspirated Black Series from AMG before forced induction. The model is entering serious collector territory as enthusiasts recognize the M156 as a milestone engine and the Black Series as the pinnacle W204. This is early- to mid-cycle for a modern classic with genuine last-of-breed credentials, fitting neatly within budget.
