As far as headroom and legroom go, there's not much difference between the BMW M4 and the Mercedes-Benz SL 550 in the front seats.

Convenience
With the Mercedes-Benz SL 550 you will definitely be making less frequent stops at the gas station than with the BMW M4, due to its tank size and fuel economy.

The BMW M4 has much less torque than the Mercedes-Benz SL 550, which generally means that it won't feel as fast or powerful.
