Video shows painstaking process of hand-stitching leather finish by Bulgarian tuner Vilner.
Bulgarian tuner Vilner shows its handy interior work in this video for the Mercedes-Benz SL 63 AMG which it has branded the Shadow Line.
Shadow Line is an interior leather finish for the SL 63 AMG and the video demonstrates the painstaking craft that goes into a hand-stitched upholstery for just the steering wheel.
The leather finish also includes the seats and door panels. The use of black and red for the leather and silver for the stitching are a set of colors that work naturally together.
The tuner also provides some unique decorative carving for the door panels - understated and very atypical for a tuner.
