The 4-Series windscreen was just redesigned for the 2014 models and is a major improvement over previous years. I've had three previous verts and the windscreens were quite flimsy and moved a lot when driving with the top down. They did not come with the vehicle and were an over $400 accessory. They also came in a zippered black bag with handles which could be stowed in the trunk (took up a lot of space). I haven't used mine yet, but hope it's more sturdy. Overall they do work well and extend our top down drive time on those nice Fall days. Be prepared for people to flash that "he/she must be freezing expression", however with the windscreen, heat, heated seats and the new "air-scarf" option - we will be all smiles... ENJOY THE DRIVE
