Condition
7
The car has had significant refurbishment and engine rebuilds, including new pistons, camshaft, ignition, carburetor, and intake manifold. It has also received a repaint in the 1990s and a more recent hood refinish. While the engine is reported to have low miles since rebuild, the tachometer is inoperative, and the doors were replaced during the repaint, indicating some compromises from original condition. The tires are also replacements.
