I am from Cincinnati and recall Dugan Buick , there was a buick, olds, and Pontiac dealer in same block all independent dealers, my best friends father was the general manager of the Oldsmobile dealer Ed Whissel olds. I remember him coming home in all the new Oldsmobile mainly the new 66 toronado and olds 442s. my friend and I used to go with him on sundays when he would test drive all the trades that came in for the week. Good memories
