Mercedes-Benz 300 SL Roadster
The Mercedes-Benz 300 SL Roadster debuted in 1957 as the more practical successor to the Gullwing coupe. While losing the dramatic upward-opening doors, it gained conventional entry, improved visibility, and refined handling from its revised rear suspension. The legendary 3.0-liter fuel-injected straight-six produced 215 horsepower, enabling a 225 km/h top speed. With 1,858 examples built, the Roadster is slightly less rare than the Gullwing but commands similar values today.
300 SL Roadsters command $1.2-2 million depending on history and condition. Numbers-matching examples with documented provenance bring premium prices. Check for rust in the complex tubular frame. Mechanical fuel injection requires specialized knowledge. Original hardtops add significant value. Most desirable are early aluminum-block engines and disc brake cars from 1961 onward.
Roadster production ran from 1957-1963 with 1,858 units built. It featured a revised rear suspension with lower pivot point for improved handling. The tubular space frame allowed conventional doors unlike the Gullwing's high sills.
