🔍 Model Background

The Mercedes-Benz SL-Class R129 (1990–1995) represented a major technological leap in the luxury roadster segment, blending refined performance, advanced safety features, and timeless design. As the fourth generation of the SL lineage, the R129 was engineered for grand touring excellence and top-down driving sophistication.

Engine options during this early production period ranged from the inline-6 SL 300 to the powerful V8 SL 500 and the flagship V12 SL 600 (introduced in 1993). These engines delivered smooth, effortless power paired with automatic transmissions and rear-wheel drive, providing both comfort and authority on the road.

The R129 introduced several innovations, including an automatically deploying roll bar, adaptive dampers (ADS), and electronically controlled soft and hardtops. Its aerodynamic styling, wide stance, and signature grille gave the SL a modern yet elegant presence that helped define 1990s luxury performance.

Built on a platform designed for long-distance comfort and sporty driving, the SL-Class R129 from 1990 to 1995 became a symbol of prestige and engineering prowess. It remains a highly regarded classic, known for its solid build quality, advanced tech, and enduring appeal.
