CWS-- I really intensely dislike the flared rear fenders you pointed out.  I also dislike the low station-wagon-like look of the long rear.  I don't mind that longer enclosed rear on a true SUV, because the higher ride in general, plus the taller windows, look more natural to me.  I don't like the Volvo you posted, either.
It's nothing particular to crossovers, I've never liked station wagons or the longer hatchbacks, either.  They all appear quite ugly to me.
Now, I do quite like the Camaro and Pontiac you posted.  And I also like the "screaming chicken" Trans Am of the late 70s.
