I'm always interested in the 'business' of collectable cars if not actually interested in owning one - that's why I went for a 3.0si over a Z4M. Absolutely love the Z4M but wouldn't dare touch one. Quite happy tinkering with my cheap 3.0si 
Z4M (all variants - breakdown not available) SORN = 544, licensed = 471 - total = 1015.
3.0Si Coupe Manual - SORN = 56, licensed = 204 - total = 260.
These graphs tell a story - more Z4M parked up / stored away than in use. Fair play to those actually using 'em.
