I recall the W powered '59 Chevy too and any low miler is cool although the Diplomat far from an exciting one..
Anyone remember the story of the 53-55 'Vette driven home from the dealer and the owner built a wall around it in the corner of his garage?.
Real story and car, I remember an article on it in Cars & Parts about '79 also seem to recall reading it was 'sprung' in recent years although the condition was far from mint..
