Fieldside Classic: The Mystery Car In The Mountains

On a recent trip to the mountains a friend pointed me in the direction of this abandoned shell of an old car. There cannot be too many if any salvageable parts left on it. The upside down orientation and encroaching trees make it hard to identify. I believe I know roughly what it might be but what are your thoughts?

Here are a few more photos that might or might not help discern the make and model.

The frame does not look too bad all things considered.

A peek inside with a few bullet holes visible.

In spring and summer I bet the vegetation makes it impossible to even spot. Any guesses on what this is?
