Ground clearance. In some parts of the US and for some use cases this is non-negotiable. It would be like buying a car in Texas without an air conditioner. There is a Japanese automaker (Subaru) that traditionally caters to this market almost exclusively in the US.
I won't buy a vehicle with less than 8 inches of ground clearance for safety reasons.
