Overview

• The lineup covers nearly the full BMW M era, anchored by a 1975 2002 Turbo and capped by a 2023 M4 CSL.
• A restored 1980 BMW M1 in M livery headlines the sale with an estimate of $600,000 to $700,000.
• Nine M3 iterations feature prominently, including a 1990 Sport Evolution estimated at $235,000 to $295,000 and an ultra-rare E90 M3 CRT showing about 104 miles.
• Three non-M entries are included: a 2002 Turbo ($115,000–$165,000), a Z1 ($105,000–$140,000), and an Alpina Roadster V8 ($350,000–$445,000).
• RM Sotheby’s listings indicate the entire 22-car collection could be bought for roughly $4.0 million to $4.2 million, with observers noting omissions such as the 3.0 CSL and any M5.
