Is the BMW M3 a good investment?

The thesis

The E46 M3 is the last naturally aspirated straight-six M3, with the S54 engine holding the production car power-to-displacement record at launch (343 hp from 3.2L). Manual examples with 12,500 built for RHD markets are increasingly hard to find in clean condition, having weathered a period of cheap ownership 2009–2012 that degraded many examples. Prices have doubled since 2019 (£13,250 then to £20,000+ now for equivalent spec), reflecting renewed recognition of this model as a modern classic. With hydraulic steering, 50:50 weight distribution, and daily usability, the E46 M3 manual sits in the sweet spot for analogue engagement at an accessible price.
