🔍 Model Background

The Mercedes 300 SL (1990–1993) was part of the R129 SL-Class lineup and marked a significant evolution in the brand’s luxury roadster tradition. As the entry-level model in this generation, the 300 SL offered a balance of refined performance, advanced safety features, and timeless design, making it a compelling choice for grand touring enthusiasts.

Power came from a 3.0-liter inline-six engine, with two variants offered during its production: the 12-valve M103 engine24-valve M104 engine (228 hp) introduced in 1992. Both were mated to a 4-speed automatic or 5-speed manual transmission, delivering smooth, responsive performance and a refined driving experience.

The R129 chassis introduced several technological innovations, including an automatically deploying roll bar, adaptive damping suspension (ADS), and fully electric soft-top operation. The 300 SL shared these advancements with its more powerful siblings, offering cutting-edge safety and comfort in a more accessible package.

Inside, the cabin featured leather upholstery, real wood trim, dual-zone climate control, and power-adjustable seats with memory functions. Build quality was exemplary, reflecting Mercedes-Benz’s commitment to luxury and durability in the early 1990s.
