How Does the 1985 Mercedes-Benz SL-Class Compare to Other Convertible?
The 1985 Mercedes-Benz SL-Class competed with luxury roadsters of its time, such as the Jaguar XJS, Porsche 911 (though arguably more of a sports car), and the Cadillac Allanté (later).
In terms of performance, the SL offered a balance of comfort and adequate power, but it wasn't a true sports car like the Porsche 911. The Jaguar XJS offered similar luxury but could be less reliable. The Cadillac Allanté, while stylish, suffered from reliability and performance issues.
Features-wise, the SL was well-equipped for its era, but lacked the advanced technology of later models. Reliability was generally good for its age, but age-related issues are common. Price-wise, the SL held its value better than some of its competitors.
Alternatives: A well-maintained Porsche 911 offered superior performance and handling. A newer BMW Z3 or Z4 provides modern reliability and features at a similar price point (used). A Mazda MX-5 Miata offers a more affordable and reliable open-top experience but lacks the luxury of the SL. Whether these alternatives are "better" depends on individual priorities (performance, reliability, luxury, budget).

Final Verdict: Is the 1985 Mercedes-Benz SL-Class a Good Convertible?
The 1985 Mercedes-Benz SL-Class is ideal for enthusiasts seeking a classic luxury roadster with iconic styling. It's worth buying if you're prepared for the costs and challenges of owning an older car. Buy used, as new isn't an option! Look for examples with meticulous maintenance records, minimal rust, and preferably one that's been well-preserved. The 560SL is the most desirable US-market trim. It's not a daily driver for most, but a rewarding weekend cruiser for those who appreciate classic Mercedes-Benz engineering and design. Thoroughly inspect the car before purchase.
