Lily Marker (Melange X3) Rear
Lily Marker was the daughter of Flash Marker, Sr., a driver who was killed by a team called the Three Roses Club. Her brother, Flash Marker Jr., rebuilt his father's car, called the Melange X3, to enter in a race and kill the Three Roses Club drivers. He controlled the car by remote control, and had Lily pretend to be its driver.
I had tried to make the X3 earlier, with dark blue instead of black and sand blue instead of grey, but gave up because the right parts didn't exist in the right colors. I then realized that due to the sometimes ambiguous colors of the anime, I could make the car with black and grey.
