I have a 1985 Mercedes-Benz 380SL Convertible, with the factory hard top and ragtop that were bought with the car. Its all original, and only 51,000 miles. All documentation of anything that has ever been done to the car is still with it. Anyone have any idea what its worth? Or a site that is like kelley blue book that has info on older cars?
