3: Mercedes-Benz 600SL
The Mercedes-Benz 600SL was a variable supercar in every sense of the word. The design and the engine were far technologically advanced compared to anything else on the market. The 600SL in particular added many modern luxury features that we take for granted nowadays, such as a power top and built-in phone (via Car Gurus).
When the 600SL hit the market, it was at the top of the Mercedes-Benz line. The blend of technology and interesting features made the car well received with enthusiasts. Another interesting thing about the 600SL is the fact that it has depreciated quite a bit in terms of value, so drivers can find them very affordably.
