MERCEDES 300 Common

As of 2026 Q1, 11,446 MERCEDES 300s remain registered in the UK — still a familiar sight on today's roads. That's down from a peak of 13,259 in 2014 Q3 — only 86% of the high-water mark, a loss of about 1,813 cars. They're disappearing at roughly 134 a year (1.2% of what's left), a pace that would halve the survivors by around 2085 if it held — though in practice the last, most-cherished examples tend to linger far longer. Tellingly, 65% 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.

About the 300

The Mercedes-Benz 300 SL (chassis code W 198) is a two-seat sports car that was produced by Mercedes-Benz from 1954 to 1957 as a gullwinged coupé and from 1957 to 1963 as a roadster. The 300 SL traces its origins to the company's 1952 racing car, the W194, and was equipped with a mechanical direct fuel-injection system that increased the power output of its three-liter overhead camshaft straight-six engine. The 300 SL was capable of reaching 260 km/h (162 mph), earning it a reputation as a sports car racing champion and making it the fastest production car of its time. The car's iconic gullwing...
