What does 'Survivor Car' Mean?

IMHO a "survivor" is a car or truck that has some value but has never been restored or modified. Sheetmetal should be original with maybe a patch or two but original paint with only touchups. Mechanical should be drivable with original engine and normal maintenance. Maybe FABO moderators should start a thread to define that term.
Once a car has been restored/rotissoried/modified it will never be original or a survivor again. I think more collectibles should be left as is. The extreme example was B-J a few years ago a survivor Mustang GT350 went for $350,000 and paint was bad and it wasn't clean.
