My GarageUsed Mercedes-Benz SL-Class Buying Guide
The SL is Mercedes' flagship convertible. The R230 and R231 with V8 power are refined grand tourers, but the folding hardtop, ABC suspension, and complex electronics require records-driven buying.
Best Years to Buy
Generations with the strongest long-term reputation.
M273 5.5L V8, refined; ABC well-understood.
M278 twin-turbo V8; refined and modern.
Years to Research Carefully
Not deal-breakers — but they reward a careful buyer.
ABC pumps, accumulators, and hoses need proactive service.
Exceptional but service-intensive. Complete history mandatory.
