Perhaps it is because Porsches (as well as many other sports cars) can actually serve as reasonable daily transportation and are fun on the track. No matter where a Porsche is, it is great to look at. Driving a Porsche anywhere is a good thing to do for your fellow man.
Most Jeeps, however will fill your ears with the sound of wind and tire roar while trying to use them as highway transportation. In addition, they look like the box they came in, so Jeep owners are doing us a public service by hiding the things deep in the woods or covering them with mud.
'Serious Off-Roaders'? I thank them!
