Description

Highlights

  • Desirable two-tone paintwork with rare medium red leather interior
  • Pre-biodegradable wiring loom model
  • Accompanied by a history file with Mercedes-Benz receipts
  • In current ownership for approximately six years
  • Previously exhibited at motor shows by a former keeper

The Appeal

The R129-generation Mercedes-Benz 300 SL is one of the most accomplished grand tourers of its era, pairing the refinement and build quality for which early-1990s Mercedes-Benz was renowned with the effortless performance of the M103 inline six. These were the roadsters that replaced the legendary R170, and while they were big boots to fill, they did so with ease.

This 1992 example is distinguished by its two-tone exterior and rare medium red leather interior. That's not a colour combo we see often for the R129, and it suits those quintessentially 90s lines down to the ground. Importantly, this is a pre-biodegradable wiring loom model, meaning it avoids the well-documented harness degradation that can affect later R129s.

A history file accompanies the car, including numerous Mercedes-Benz receipts. A previous keeper was known to show the car at motor events, and the vendor reports approximately six years of trouble-free motoring during the current ownership. With a valid MOT through to September 2027, this 300 SL is ready to be driven and enjoyed straight away.
