OK, I know this is a long shot, but I have to try. Years ago I sold a '70 Stage 1 hard top 4-Speed car VIN 446370H169734. The car was Burgandy with brown vinyl top, and had Burnished Saddle buckets. This was not a Buick recommended color combination, and I distinctly remember the code Z189 on the body tag. The car went to the Cincinnati/Northern Kentucky area as I recall, but it could be anywhere now. When I sold it, it had the original engine and trans, but not the carb and distributor. It had the consolette, but lacked the shifter. The entire front clip was missing. The car seemed to fall off the map. I have not seen it since, and it is not in the Stage 1 registery. I would love to get it back if it still exists. Hopefully with the original engine and trans. Does anyone know of it's whereabouts? I know......good luck!
