Its all about image, not practiclity.
Have you checked to see what the best selling cars are lately? Same as they have been for over a decade: Camry, Accord, Carola, Tauras, yeah those babies are all image.
On the truck end you're looking at the F150, the Explorer, the Trail Blazer. Not much better than the car list. You're really working that image rolling up on the Starbucks in that creaking, weazing Chevy Blazer.
What people want isn't the same as what they buy, or what they say they would buy. Focus group 101. While a porsche may stir something in the collective unconcious of us all, few of us pony up at the dealer. A shame, if you are going to drop 30k on something you loath, why not pop 45k for something you'll love and get better resale from?
