Brand Image - Venn Diagram
I think brand image could be a really interesting aspect of the game. It is both exciting to see where your brand goes but also where the other brands are. It gives you a quick perception of what the buying public might think about your cars.
So my thought was to have Brand Image fall into a number of categories basically like a Venn Diagram. Such a diagram could even be used as a menu item quick glance for the user to see how they stack up against the other car companies.
Anyways, just throwing it out there - take it or leave it just thought I would fuel the fire.
PS: Just threw in some examples of brands and maybe I didn't put them exactly in the correct brand image segment, personal preferences may vary

(hope the attachments work)
