"The Lost Highway" by L.A. Mitchell:  

On a desolate west Texas highway, a man at a crossroads in his life meets a beautiful woman, lost in more ways than any cardinal point on a map.  Her pristine 1959 Thunderbird, her matronly dress and her optimism conspire to place her firmly out of touch with reality.  In a race against the clock to reconnect with an old love, he discovers the captivating stranger has driven straight out of her own time and into the abandoned shell of his heart.
