Background
The Mercedes-Benz SL-Class is a grand touring sports car in series production since 1954. The designation SL derives from the German ‘Sport-Leicht’, or ‘light sports’.
Initially, the first SL was the 300 Grand Prix racing car built in 1952. At the time, Mercedes-Benz had no intention of developing a road-going version, but in 1954, American importer Max Hoffman suggested a street version of the 300 SL be produced for wealthy performance car enthusiasts in the United States where the market for the personal luxury car was booming. The rest, as they say…
The fourth-generation R129 as offered here was introduced in 1989 and was a revolution compared to the ageing and square-cut R107 that preceded it. It was the first Mercedes-Benz model to have the hydraulically-operated roof open and close at the touch of a button, a 48-valve V8 engine and projector lens HID headlamps (from 1995).
Other ‘firsts’ for the R129 convertible roadster included an automatically deployed roll-bar in the event of roll over. Alternatively, the driver could raise or lower the roll-bar again with a touch of a button, if desired.
In 1998, the R129 received major cosmetic and technical updates with revised engines to include the V6, V8, and V12 engines from the new W220 S-Class saloon. Updates includes a new steering wheel, curved taillights, 17-inch alloy rims as standard, Nappa leather seats and body-coloured door handles.
More importantly, the V8 was swapped from the 32-valve dual cam M119 unit to the 24-valve single cam M113. While power was reduced to 298bhp, this engine is regarded by many as being superior, courtesy of its lightness and enhanced efficiency.
