my experience is that most who ask 'is that original' mean 'has that been restored, or just well taken care of and little used' - unless they're looking at some detail like under the hood or inside
a guy walked by as I was getting outta the 58 last night and said 'nice truck' and his parting remark was 'what I like is the originality'
very few are thinkin about updated driveline, disc brakes, 'factory correct' colors or radial tires, they're just talkin about the overall look and wondering if it's a "survivor" or something a bucket of money and a lot of time went into
