BMW M635 CSI Rare
As of 2026 Q2, 258 BMW M635 CSIs remain registered in the UK — a genuinely rare sight on today's roads. That's down from a peak of 262 in 2025 Q4 — only 98% of the high-water mark, a loss of about 4 cars. Numbers have held broadly steady over recent years rather than falling away — often the mark of a model that owners deliberately preserve. Tellingly, 72% are declared SORN — kept off the road in garages and barns rather than driven, the signature of a car being looked after rather than used up. In all, the BMW M635 CSI is rarer than 50% of the 2,315 UK car models we track.
