Hi, I'm trying to find some history of my '64 Corvette. It was delivered new in 1964 at Bob Burrow Chevrolet, Barrington IL (dealer code 86, zone 11). I have a 1989 Spinner concourse certificate (Chevy Vettefest) and a 1992 Certificate of participation at Bloomington Gold. The car was imported to Switzerland in 1994. I have been able to find old invoices from Bob Burrow but none of them concerns my car. Any hints on where I could start or look ? Thanks a lot !
