Last Of The Real Mercedes

By far the best Mercedes I have ever owned. I might say the last of the real Mercedes. 2015 SL400 may be the last real Mercedes.

5.0

The smoothest car I have driven in a while

This car is the perfect car. Its ready for anything and occasion. A drive to the beach is the greatest thing to do with this car

5.0

SL 400 Phenomenal blend of sport & luxury

I needed a comfortable cruiser with sport driving capabilities. This car has it all with a manual shift mode and sport suspension setting for driving the mountain roads where I live. I never get fatigued or uncomfortable on long rides due to the excellent seat design, with massage built-in. The six cylinders are what I wanted, didn't need eight. The way it is designed, the torque and bi-turbo let you cruise at low rpm yielding a surprising 27 mpg highway. But it will push you back in your seat when provoked. Final note, the cornering is so flat you would think you're riding in a go-cart.
