Expected to the upcoming Detroit Auto Show, Z4’s special edition features a very fancy internal coating, which combines ivory and brown wood to caramel and black accents as you can see by clicking on the article’s picture. Both seats and sunshades are made of Nappa leather, the first in ivory and the second in black. Besides, this Z4 comes only in the exclusive Sparkling Brown and brings the aerodynamic M Sport kit as standard, composed of side spoilers and more aggressive bumpers. The price wasn’t revealed yet.
