On hwy 49 just east of 109 there is a junk yard that has a mustang up on a pole at the road. The last time I was there (2-3 years ago) he had adout 5 of them that looked to be in good shape.
i considered myself a true jeep fan, but i've never seen one of those even in pictures. but i sure do like it. i do think the gladiator is a bit of a better upgrade though.
