I saw this movie on TCM tonight. Kinda weird, but overall pretty good.
Only 2 cars in the movie:
1965 Ford Thunderbird, 4 stars - Used throughout the movie and plays a key role in a few sequences. Visible from all angles, definitely 1965.
Ford F-Series, 2 stars - I don't know the model year, but it looked kind of old and beat-up.
