There are three nice shots of a 73 Riviera in this movie.
In the first one Nick Gace was almost ran over by the Riviera
The second one shows the Riviera jumping in front of the train
Third, the left window is blown out by a gunshot, nice view at the rear inside of the car. Dennis Hopper then says with a strong Texas accent "this ol' V-8 purrs like a cat!"
