Very cool, with lots of potential, but definitely not done. The biggest annoyance is not being able to pick (or even differentiate) between different models of a particular brand. For instance, there are 117 BMWs, but no way to view just the 335i models, either with an actual filter, or even visually. Mousing over 117 dots = not fun. Also, a legend that explains dot size and color would be super easy to implement and tremendously helpful.
