Where did this car go? I know it's a long shot..., Trying to find my mother's 914 from the 70s Options

[amphiduck]

My mother just recently unearthed some pictures of her 914 that I believe she bought new in the early 70s. From the pictures, it looks like it would be a 70-72 model, but I'm not sure. Any light on the subject as to what year this car could be? Also, she doesn't have a VIN or license plate number, but she did sell it in the Chattanooga, TN area sometime in the mid-late 70s. Her name before she married my father was Barbara Cunningham, now Barbara Brown. I'd love to find out if it is still around, but have no clue how to proceed.

Thanks for the help!

And the doberman in the picture was Dirk, who my mother claims rode shotgun several times.
