One day my wife brought home a 1993 Pontiac Grand Prix she had bought. She pulled it into the garage and parked it next to my all-original 1961 Norton Manxman and I was stunned to see that it's paint matched exactly. I have looked up the paint code for this car and it is wa9614. I put my face right on this car and the fuel tank for the Manxman and the match was amazing.
Check out this auto painted in the color here:
