I see your car was a RETAIL order- same as my convertible. RETAIL orders are where a customer came into the dealership and specified how they wanted the car equipped.
And they are both 72 models, Q codes and both have a VIN ending in "000". Your is the first I have seen to share this "000" sequence other than mine. I'm sure there are others.
The PO who restored it did. He did a rotisserie restoration on it, so there is no signs of the old paint. I was a bit reluctant to buy a color change car, but it is very nicely done.
