I have a 2015 M4 convertible. With the windows up and the factory wind blocker installed behind the front seats, there is almost no buffeting in the cockpit. Very impressive. But...with four passengers...not so much as the wind blocker is stowed. It would be nice if there were some sort of black, elastic wind net or blocker that could be stretched between the rear seat headrests to effect some level of wind control when there are passengers in the back seat. Would love to hear if anyone has seen anything out that that would also be somewhat attractive and effective.
