I have to say that the part I like the best are the angles that been formed in the driver's seat.
The dramatic gesture, well, a strange coincidence when I put the layer and then, put it in the place
about the door, is a 2x3 plate, and I put in red and black, but it doesn't look good with the design, I even try with white plates or with 2x4 plates... the door is the most unconfortable part of the cart, at last, I feel confortable with the dark grey 3x2
