"Preservation," as opposed to full-on "restoration," is a relatively recent trend for car collectors, said Hammers.
A couple of decades ago, a barn find car would have been restored, or returned as close as possible to the way it would have looked the day it left the factory. (Or, in some extreme cases, even better.)
"In the '70s and '80s, everything got restored," said Hammers.
In a preserved car, the clock is simply stopped, its true age is respected and there's no attempt to make it look like new.
