The 1 Series convertible's options list includes the Moonlight Black soft top with shiny metallic fibers that produce a metallic silver appearance in sun- and moonlight. The convertible's optional leather upholstery also features BMW's exclusive sun-reflective pigments, which the company claims can lower the seat surface temperature by up to 20 degrees.
