There is an Eighmey Buick dealership in Troy PA, phone number (570) 297-2148. The head guy there is Veril Eighmey, a very fine gentleman up in his 80's. He still goes to work every day. I live just north of the PA - NY border in the Elmira NY area, and have done business with Veril. At his age, he should be able to go back a few years with family history. Good luck. Bill
