Originality-does it matter?

I'm the odd man out here. I was never in the market for an early A body until I came across my car in the parking lot of an industrial park in Newark CA. It had "for sale" written across the windshield, and being a Mopar guy that has owned 16 Plymouths, just had to have a quick look. It turned out to be a real Formula S car (I like rare cars), one of 2,994 FS cars built in '65. Not only that, but it was a San Jose CA car, kind of beat up but very little rust, with the original high performance 273 with correct date code (12-2) built 12 days before the car's scheduled build date (12-14) Factory tach was still in place and had remnants of the factory black stripe as well. I have stuck to originality for the most part but have made concessions for upgrades including radial tires with 15" rallyes, 1.03 torsion bars, Borgeson steering box, flip top gas gap, and updated the factory radio. I'm nearing the end of a 15 year project that included complete disassembly with paint in the factory colors.
