Maybe start with an NICB report.They are hard to get,but at least it would tell you if the car was sold new at a dealer in that area.After that,sand the car down and see what colors it was when it had the Motion paint on it.I heard that there were a few 73's converted when new that had white interiors.There werent many "new car" conversions done on 73 Camaros,and it is speculated that only a few came from Baldwin at the very begining of the 72 season when some 73 cars were sent out as dealer stock to make up for the 6 month shortage of 1972 cars.I think those were the 3 supposed white interior cars but I cold be wrong.There could have been many 73's converted as used cars in later year,thats goin to be hard to document without Joel's assistance.If your plans were to sell this car for more money because ofit's Motion pedigree,it wont mean anything until it has a letter from Joel.
