Notice the owners folio lists the owner as "Klares collection"
"Klare" would be Klare Sunderland. He's a big car dealer in Mechanicsburg PA.
Notice the badge on the Caprice says Sunderland motors. It was his dealership that bought the car from GM. Can't begin to guess how it ended up in CALI.
He & his family own an MB dealership:
I see a few of his cars down here in the summer.
