Is the BMW M3 CSL a good investment?
E46 SMG (2003–2004)
The thesis
The E46 M3 CSL is now trading above £150k in the UK, with median auction price £82k and top examples hitting £178k in Europe (Oct 2025). It's the purest M3 ever made—110kg lighter, carbon roof, 360hp S54. SMG transmission is controversial but part of the CSL's character; no manual was offered. Already appreciated significantly but still below Ferrari 360 manual money despite greater rarity and driver focus.
