1939 Packard Twelve conv. sedan for sale on BaT in CCCA - General Posted August 1 The Missouri dealer's web page for this car, with the McCormick story, is still online. The description says "With incredible provenance..." Maybe there should be an unwritten rule that says "incredible provenance" usually means "non-credible provenance." This is a good reminder that you must always do your own homework on any claim of an unusual feature in a car's history, if the feature is considered part of the car's value. Thanks, 27stutz, for making truth available. You've made one small corner of the old-car selling world a little better.
