B - Build quality
Build quality - The standard of a car's construction. Generally, well built cars look and feel very solid and use high-grade materials throughout. There are exceptions, such as the Subaru Impreza, which is very well built and long-lasting, although some of the trim materials look cheap.
Build quality can also be judged from the neatness and close fit of body panels and the regularity of the gaps between them. The tighter and more regular, the better.
