Poland-based Carlex Design is known for designing and manufacturing incredibly unique car interiors. You might remember some of their steampunk-inspired numbers from the past. For their latest project, they decided to customize a first generation BMW Z4 Roadster. It features a V8 engine from the previous M3 model, a two-tone silvery and grey exterior with gun metal allow wheels, custom bumpers, a qual exhaust system and a custom carbon fiber diffuser. However, it’s on the inside where the real work is done. Upon entering, you’ll find black Alcantara and buffalo leather, along with hand-painted carbon fiber accents that offer up a beautifully sleek and luxurious look. Take a closer look below.
