I happened to be watching an 8mm home video of a German family visiting Pattaya in the late 70’s and spotted what could very well be my MS-60 Toyota Crown:
It seems to be the right color and model, and these cars were originally used for government bigwigs, so it’s possible that one of them parked it right in front of the Regent Hotel back then. I’m not sure of the number imported back then, but I’ve heard stories of a parking lot filled with old ones out of service. Wish I knew where it was!
