I can honestly say I have never looked at car ratings when buying a car. I simply see something I like and buy it.
I get a lot of rental cars for work.
Once I was in the market for a new one of my own, I bought the make/model that I liked.
Drive around Ankeny, West Des Moines, Johnston, Waukee and all you'll see are trucks, minivans, and SUV's. The people buying new vehicles have been gravitating towards bigger vehicles for quite some time.
They better hope petroleum prices are low for a long time.

Toyota, Honda, and Hyundai would eat them alive if gas went back to $4+ per gallon.
