The first thing to consider is that if you plan to keep a new vehicle is to figure that at over five year ownership the cost of unleaded regular will average at least $4 per gallon. If high when you go to trade it will affect resale negatively and good gas mileage doesn't seem to harm resale even when gas is cheap because the used vehicle buyer. Used car buyers tend to have less money and nowadays you can buy a calculator at a dollar store. Used car buyers have always liked "gas sippers". over "gas guzzlers". Again, figure $4 per gallon gas.
There is a huge glut of new "gas guzzler" vehicles out there compared to demand. When car sale people see a "conspicuous consumption" person like Traci walk in I can imagine them thinking "Thanksgiving is coming early this year."
As for the Japanese Vehicles during last winters bad cold snap I noticed that most of the vehicles with mechanical problems were "rice burners" five years or older. Japanese has a temperate climate and they export most cars after three years. mostly to warmer or coastal climates so I wonder if their engineers really understand the cold.
