I understand that Endeavor was made of many "spare parts" and brought up to spec.

NASA scrambles to fix shuttle leak
CAPE CANAVERAL, Fla. - With a launch countdown looming, NASA scrambled to fix a cabin leak aboard space shuttle Endeavour on Wednesday.
The leak was traced overnight to one of two pressure-relief valves in Endeavour's crew cabin, located behind the toilet but separate from the bathroom plumbing, said NASA spokesman George Diller.
NASA decided late Wednesday afternoon to replace the bad valve with one taken from space shuttle Atlantis. The newly installed component will be tested Thursday
Scavenging parts from Atlantis makes me wonder if someday, we will find an old shuttle up on cinder blocks in NASA's back yard being used as a "parts car".
