NGK V-Power out of my '92 Lumina, only 42k miles; old vs. new.

What "V" groove?

This car has a waste spark ignition system. They're hard on plugs because they fire twice for every crankshaft revolution.

the 3v engines had plugs that would break when removing, very common. The 2v engine would spit the plug and pull the threads, not as common but did happen.
