PROTON SL Ultra-rare
As of 2026 Q1, 43 PROTON SLs remain registered in the UK — one of the rarest cars in Britain on today's roads. That's down from a peak of 155 in 2014 Q3 — only 28% of the high-water mark, a loss of about 112 cars. They're disappearing at roughly 1 a year (1.4% of what's left), a pace that would halve the survivors by around 2074 if it held — though in practice the last, most-cherished examples tend to linger far longer. In all, the PROTON SL is rarer than 68% of the 2,429 UK car models we track, putting it firmly in 2026's endangered class.
