Wifey signed us up for Prime video and so far I can't find "Two Lane Blacktop", "Heart Like a Wheel", or "Vanishing Point" in the list of movies. Don't know what the deal is with that. Prime does have "Bullit" and "Dirty Mary, Crazy Larry".
I'll bet you can buy DVD's of those three really cheap. I've got a collectors edition of DM/CL & VP. Heart Like a Wheel I don't have.
