I bought a new '80 Buick at Davis Buick in Centerville after they had moved from Dayton. Shortly thereafter they became Bob Ross Buick. Shannon Buick was in business in the fifties, at least by 1951, so Davis Buick did not become Shannon Buick. Reichart (sic) Buick (formerly Shannon) is on Salem Avenue. It never was on Main St. You better go back and study-up.
