A wind deflector for a Mercedes 380 SL, 450 SL, 560 SL Convertible, is the essential convertible accessory: It is the single most effective and unobtrusive way to reduce strong and noisy wind gusts while driving. Instead of the wind blowing through the cabin of your Mercedes convertible, up to 75% of the wind is diverted over the back of your convertible. You can soak up the elements instead of being at their mercy. Extend your top-down convertible season: Your wind deflector will redirect the wind over the rear of your convertible. You can drive with the top down earlier in the Spring and later into the Fall and in more comfort all year long. Enjoy driving in peace and quiet: Without the loud rush of wind in your ears, you'll finally be able to listen to music and talk with passengers. The difference is dramatic, especially when traveling at highway speeds.
