Is the BMW M3 CSL a good investment?

The thesis

The E46 M3 CSL is widely regarded as the last raw, unfiltered M car: 355 hp S54 straight-six, 243 lb lighter than the standard M3, SMG-only, and Europe-only (zero US allocation). Limited to 1,383 units globally, with 535 in RHD. The median price sits at £82,410, and recent sales show prices stabilising between £66,000–£178,000 depending on mileage. It fits the brief perfectly as a naturally aspirated limited edition, though the cycle has moved from early appreciation into mid-phase consolidation. Desirability remains very high among BMW purists.
