AIXAM 400 Ultra-rare
As of 2025 Q4, 1 AIXAM 400 remains registered in the UK — one of the rarest cars in Britain on today's roads. That's down from a peak of 2 in 2015 Q1 — only 50% of the high-water mark, a loss of about 1 cars. Numbers have held broadly steady over recent years rather than falling away — often the mark of a model that owners deliberately preserve. In all, the AIXAM 400 is rarer than 93% of the 2,408 UK car models we track, putting it firmly in 2025's endangered class.
