Description: The introduction of the R129 marked a significant step forward for Mercedes-Benz’s long-running SL lineage, combining traditional engineering integrity with advanced safety and comfort technology. Launched in 1989, the model was widely praised for its build quality, refinement and usability, and remains one of the most accomplished modern classics from Stuttgart. At the top of the early range sat the 500SL, powered by the formidable M119 V8, widely regarded as one of the marque’s finest engines.Offered from a private Collection, this 1991 example is finished in Arctic White (147U) over Royal Blue leather (272A), a timeless and elegant combination that complements the clean lines of the R129 particularly well. The interior is paired with a matching blue soft top, ensuring a cohesive and period-correct presentation throughout. The car retains its correct Gullideckel alloy wheels, further supporting its originality.Displaying 34,251 miles at the time of cataloguing, the car has clearly seen light use throughout its life. Although it has had seven former keepers, it has remained with its current owner for close to a decade and has been maintained with evident care during that time. Since 2016, it has been supported by independent servicing and will be supplied to its next custodian with a fresh service and MOT.This example is well specified, with factory features including heated seats, air conditioning, cruise control, driver airbag and the R129’s automatically deploying roll-over bar, all of which contribute to its reputation for safety and refinement. It also benefits from a rare rear seat conversion, enhancing practicality without compromising its character.Power is provided by the 4,973cc M119 V8, producing approximately 326bhp when new and paired with a 4-speed automatic transmission. The result is the smooth, effortless performance for which these cars are renowned, with strong torque delivery and refined cruising capability. Contemporary figures quoted a top speed in excess of 155mph, highlighting the model’s performance credentials.The history file includes MOT records supporting the low indicated mileage, together with a clear HPI report. The car is also accompanied by its original book pack and purchase invoice, adding further appeal.Well specified, attractively presented and evidently well cared for, this R129 represents a compelling opportunity to acquire a low-mileage example of one of Mercedes-Benz’s most respected modern classics.
