The Mercedes-Benz SL-Class R129 was built from 1989 to 2002.
The SL500, the most traded version: The R129 SL500 represents Mercedes-Benz at its most confident, bridging the gap between the classic Pagoda and modern luxury. Launched in 1989, this generation introduced the revolutionary pop-up roll hoops and pioneering ASR traction control, setting new safety standards for convertibles. The 5.0-liter V8 delivered 322 horsepower through a buttery-smooth 4-speed automatic, providing effortless autobahn cruising with genuine sports car capability. Bruno Sacco's timeless design aged gracefully over its 12-year run, with later models receiving the improved 5-speed transmission and refined interior appointments. Production exceeded 200,000 units, making clean examples accessible while exceptional low-mileage cars command premium prices. The SL500 remains the sweet spot of the R129 lineup—more reliable than the V12 SL600, more characterful than the six-cylinder variants. Today's collectors appreciate its blend of '90s Mercedes build quality, analog driving experience, and modern conveniences that make it genuinely usable.
