MERCEDES 350 Uncommon
As of 2026 Q2, 1,462 MERCEDES 350s remain registered in the UK — an increasingly uncommon sight on today's roads. That's down from a peak of 1,505 in 2021 Q4 — only 97% of the high-water mark, a loss of about 43 cars. Numbers have held broadly steady over recent years rather than falling away — often the mark of a model that owners deliberately preserve. Tellingly, 44% 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 350
The Mercedes-Benz SL-Class (marketed as Mercedes-AMG SL since 2022) is a grand touring sports car manufactured by Mercedes-Benz since 1954. The designation "SL" derives from the German term "Super-Leicht", which translates to "Super Light" in English. Initially, the first 300 SL was a racing sports car built in 1952 with no intention of developing a street version. In 1954, an American importer Max Hoffman suggested the street version of 300 SL for the wealthy performance car enthusiasts in the United States where the market for the personal luxury car was booming after the Second World War.
