I saw two here in Colorado Springs last week, oddly enough. Both white on white, and both had hard tops on. They might have possibly been the same car.
Saw two near Austin, Texas in June, one an open convertible, silver blue, and the other red, with the hard top on.
The first one I ever saw, as best I can recall, was in Hilo, Hawaii in late 1968. I was standing just in front of a bridge, probably shirtless, trying to hitch a ride back to Ookala, and a striking woman zipped by in an open 113. I distracted her, I guess, and she swerved to correct her path after looking at me and glanced off the curb on the bridge. I hoped she would return for her hubcap, but she didn't. If she had, perhaps my life would have been different. Her hair was blonde, I recall, but I don't remember the color of the car. Now, I would remember the color of the car and not the other details.
