The 3 Series convertible, for the first time, is available with a 3-piece folding aluminum hardtop roof. The new convertible is also the center of many new technological advancements for BMW as well as the recipient of many existing safety and performance technologies that have been improved upon for the new model. The new 3 Series convertible improves upon BMW's "Comfort Access" option, by allowing the user to completely raise and lower the folding roof by simply pressing and holding the respective buttons on the key fob.
