Harry Truman's 1953 Chrysler New Yorker

I'm researching a book on Harry Truman and would like to locate his
1953 Chrysler New Yorker (it's black with chrome wire wheels). I am
told it is owned by a collector, but I have not been able to locate
him (or her). (It's not at the Truman Library.)

Does anybody on this group happen to know where Harry's
'53 Chrysler might be? Or, can anyone offer any advice on how to find
it? Thank you!
