After all SUV's are too expensive for average families to afford...
=============
Not sure what you mean by "average families". My husband is a car/truck saleman for Dodge. What with incentives, rebates, specials, etc. etc. etc. a lot middle class ("average") families can, and do, lease them (actually buying one is much more expensive). But in this neck of the woods (central Ohio)lots more Caravans than Durangos go out the door.
I was being sarcastic. My friend, the enviro wackos have no idea why Americans keep on buying SUV's and this misguided stunt of theirs will make the dreaded vehicles even more popular with the car-buying public. The genie's already been let out of the bottle and SUV's went mainstream awhile ago.
