*::::::Since I deny that there is a primary use, some of this is irrelevant. The rest involves a question over which B2C disagrees with most other editors: if we have a system of article names (here including Buick Regal and Honda Civic) may we reasonably conclude that many readers will notice it, and come to expect Chevrolet Corvette, which thereby becomes natural and obvious even for those who would not have used it to begin with (some would find it natural anyway)?  I think so; most people do; B2C insists not. I have spent more time on that discussion than I care to admit; I will not spend more.
