The sixth-generation Mercedes-Benz SL, known as the R231, was produced from 2012 to 2020. Its most significant engineering feat was a new all-aluminum bodyshell, which cut weight by up to 308 lbs compared to the previous R230. The model lineup included the V6-powered SL 400/450, the popular V8 SL 550, and the high-performance SL 63 AMG and V12-powered SL 65 AMG, all featuring a retractable hardtop.
The R231 appeals to buyers seeking a modern grand tourer with a blend of luxury, technology, and all-season usability. The folding "Vario-Roof" offers coupe-like security with open-air enjoyment, and optional features like Magic Sky Control and Airscarf enhance the experience. The AMG models, with their bi-turbo engines and enhanced dynamics, provide serious performance, with the SL 65's V12 being a status symbol of effortless power.
Having undergone significant depreciation, the R231 market offers substantial value. Average prices sit around $41,000, typically for well-kept SL 550 models. The market spans from early, higher-mileage V6 cars to pristine, late-model SL 65 AMGs that can still command prices up to $185,000, reflecting the wide breadth of performance and specification available.
Buying Tips
- Check the complex Vario-Roof folding hardtop for smooth operation and inspect for water leaks, particularly in the trunk and around the A-pillars.
- Many cars have the Active Body Control (ABC) suspension, which is expensive to repair. Look for sagging corners, dashboard warnings, and service history for the pump or valve blocks.
- On M278 V8 engines (SL 550), listen for a brief rattle on cold starts, which can indicate failing timing chain tensioners.
- Test all interior electronics thoroughly, from the COMAND infotainment system to driver aids, as diagnosing faults can be costly.
- A complete service history from a Mercedes-Benz specialist is essential, as deferred maintenance on these complex cars leads to expensive repairs.
Prices based on recent auction sales range from $5,625 to $185,000, reflecting the wide variety of model years, engines, and conditions available.
