Another way to say this is: what is the standard deviation for each model? For some cars like the Insight, the "outlier" cars are shockingly far apart from each other.

A consistently high mean with a lower standard deviation will give potential buyers comfort that the driving style and location is not going to result in a massive variance from the norm.
