Vanishing wrecking yards

The newer cars are mostly plastic...decent Mopars started disappearing in my area in the 90s, that was exacerbated by parts sellers getting there first and buying whole cars to "part out" etc. If you worked for a living and got there Saturday, the Valiant that came in on Wednesday was gone for example. Plus you had hacks who would smash the rear glass out of a Dart two door to get the rear window stainless off instead of removing it the right way with the tool...
