Mercedes-Benz 600SL
The Mercedes-Benz 600SL is by far one of the most well-known roadsters on the classic car market. The 600SL was the car that put Mercedes on the map in the 1990s when it came to innovation and technology. The car was also powerful with a smooth-running V12 engine and style (via Car Gurus).

Like most cars from this era, the 600SL has depreciated quite a bit. Although a low mileage example will set you back a pretty penny, a regular run-of-the-mill used model with some mileage on it is affordable. The Mercedes-Benz 600SL is a car that stands out from the crowd when it comes to performance and styling.
