The Mercedes R231 SL

Mercedes-Benz SL R231: 2026 EditionHistory - Technology - Buyer's GuideA comprehensive guide to the aluminum-era SLIntroduced in 2012, the Mercedes-Benz SL R231 marked a major turning point in the history of the SL. Its predominantly aluminum bodyshell reduced weight substantially while combining impressive structural rigidity with the comfort, refinement, and effortless performance expected of a Mercedes-Benz roadster.
A particular strength of this updated 2026 edition is its detailed buyer's guide. Although the R231 is a highly capable and desirable modern classic, its advanced technology makes a careful inspection essential. The guide explains what prospective owners should look for when assessing a used example, including the vario-roof, roof hydraulics, drainage system, ABC suspension, electronics, and other potential problem areas.
It helps readers identify well-maintained cars, recognize warning signs at an early stage, and avoid potentially costly mistakes. The book also explores the development, technology, and model history of the sixth-generation SL in detail. From the elegant SL350 and SL400 to the powerful V8 models and the formidable V12-powered SL65 AMG, it covers the full range of R231 variants. It explains the important changes introduced during the model's production life and places the R231 within the long tradition of Mercedes-Benz luxury roadsters.
