I started perusing the original documents this evening and there is a ton of stuff! It actually surpasses my old Hemi Charger in terms of a paperwork archive. There are two copies of the order sheet, a handwritten yellow pad of the options and costs, the hand written purchase order, the typed sales invoice, the two page window sticker, the original loan agreement for $2200, the paid off loan agreement, the satisfaction of lien certificate, a 1973 Pontiac brochure that lists the SD455 as an available option in the Lemans, and Grand Am, the Pontiac Wide Track records booklet with all the various warranty pamphlets, the two owner's manuals, the odometer statement, a letter from Pontiac congratulating Rick on his purchase, and even the adding machine tape denoting the sales price minus the loan amount:
And all of Rick's New York registrations from 1973 to 1975 and the Arizona registrations as well. It even lists the original license plate 956-LYS. I just ordered a reproduction of that plate from the same place that made the replica Ontario plate for my black car.
I also have all the registrations and sales transfer docs from Rick to the second owner and third owners as well. It appears that Rick sold the car with 16,165 miles. The second owner sold it with 16,744 miles and the third owner sold it to me with 18,878 miles.
