While I agree with that statement, I do know that stereotypes get created from several people having the same experience.
Like the Harley comments that were made earlier. The thing that people have seen over and over again is that Harley owners are mid life crisis men who have plenty of money and want to play tough. I have known plenty that are great guys and just like to ride for the sake of riding.
Same thing with Jeep drivers. They buy the jeep and the personality along with it. Again, I have known great and nice people that have owned or drive a jeep and are nothing like that stereotype. But when people live the mentality of "Its a jeep thing, you wouldn't understand." That's exclusion of everyone who didn't purchase a jeep.
I haven't had much experience with "jeeper creepers", but I have had experience with people being exclusionary because they purchased something that they perceived to be better than mine, making them better than me.
I think its that mentality, not the vehicle they drive that is the heart of the trouble that Marlin ran into.
---I will add that I have wanted a jeep ever since I was little and wanted to be just like MacGyver
