The Mercedes-Benz 300 SL was the first iteration of the SL-Class grand tourer and fastest production car of its day! Only 1,400 300SL coupes were built, and a really nice one is valued at a cool $700,000. Most are in top shape because this auto is one of the most revered sports cars in history and few owners risk driving on public roads.
The Gullwing was virtually indestructible--one reason it beat more powerful cars such as Ferraris in races. Rugged and brilliantly engineered, you could drive the 300SL coupe all day at top speed if roads were clear. The Gullwing was fast partly because it was highly aerodynamic. For example, its engine was tilted 45 degrees to allow an especially low hood line for less wind resistance, which was highly unusual at that time.
