It was actually otc that deemed my ride a douchemobile. If I remember his post correctly it also enumerated the sin of doing a lot of things well but not being a stand out in anything. I suspect "anything" encompassed neck snapping acceleration, gut twisting cornering, etc. but he can fill us in on that.
I don't but they come standard. I can tell you they fit two regular size adults comfortably though. For instance, when we were in Paso with two other couples, we all took the douchemobile out for dinner and everyone fitted comfortably.
