Thursday Twister: What is a Wagonback

This next Thursday Twister comes as a suggestion from Kaibeezy (DT resident logo guru and idea man), and it is a bit more twisted than the average twister. In a normal Twister, we ask for readers to identify cars that contain certain identifiable costmetic features (pop-up headlamps, forward hinged hood, etc) but today we are looking for cars that contain an undefined, but unmistakably odd-looking and noticeable feature -- the wagonback.
