On the Surface:

A beautifully presented and incredibly rare example of the ‘SL Edition’ SL320. This is one of just approximately 150 right-hand drive Designo models produced. Finished in Mystic Blue over a Black leather interior with just 19,003 miles from new, this example remains in exceptional cosmetic condition—clearly cherished throughout its life.

Maintenance & History:

This car has enjoyed long-term private ownership. It remained with the first owner until 2015 when it was acquired by The Vendor—a Mercedes-Benz Club member—from Avantgarde Cars in Tamworth. It was subsequently transferred between family members (brother-in-law, vendor again, and sister) purely for administrative reasons, and has remained effectively in the same careful hands. The Vendor's sister has not driven the vehicle during the 4 years of registered ownership. Supplied with its original leatherbound Mercedes-Benz book pack, the car includes a comprehensive collection of documentation: original owner’s manuals (including SL Owner's Manual, Driving Manual, Technical Data, Interior/Exterior Guides), the original service book with 6 service stamps from 2001 to 2017, plus a seventh service recorded in 2020 in a supplementary book. A well-documented history file contains a large collection of invoices, MOT certificates, and an original Mercedes SL brochure booklet, supporting the car’s mileage and diligent upkeep. The SL has covered just 500 miles since 2015 and approximately 4,000 miles over the last 20 years.

The Model:

The SL320 Designo ‘SL Edition’ marked the swansong of the revered R129 generation, combining the elegance of the late-model facelift with exclusive Designo enhancements. Powered by the 3.2-litre V6 engine paired with a 5-speed automatic gearbox the Designo features include a special-order Mystic Blue exterior, unique trim and upholstery, special plaques and additional styling cues. These final editions are among the most sought-after R129s.

Sale Insight:

Opportunities to acquire one of the very limited ‘SL Edition’ Designo R129s are rare—and rarer still in this condition, with low mileage and ownership history. With just over 19,000 miles from new, meticulous documentation and long-term Mercedes enthusiast ownership, this is a standout example ideal for collectors and enthusiasts.
