That's a family heirloom. I am amazed at my 12 owner car with zero rust. Even the door bottom edges are crisp. Mine WAS Palladium Silver and long ago painted white. Whoever painted it simply wanted white. There's no body work. I pulled the original interior door papers back and it was also white. I assume the big Ws written inside each fender meant white....Heard from a collector that Pontiac repainted leased cars. TRUE?
