Dodge Bros. promo film...

I wish to heck I could remember the movie. Just saw it late one night years ago. It was a "Tom Mix" sort of movie, and might even been Tom Mix. Cowboy-ish, western-desert, 20's something, something about a girl (the heroine!!) getting kidnapped. The hero was driving this beater of a 20's touring car all over rocks, humps, ditches, a real hoot. At one point you could see it coming up from over a rock and see the frame twist from stem to stern. Doors falling open, LOL
