Took a drive over to Twin City Buick in Maryville Tennessee today. This was the dealership listed on the original window sticker. The local library had pictures of the dealership "back in the day," so I parked out front of the old building too.
...not unusual; depending on when they started, I've seen dealer names go from a generic name to specific brand, and as brands come and go/lose market share/foreign competition, take on other family brands and even foreign ones, to stay afloat. Sometimes makes finding correct era tag frames/emblems difficult, not to mention the Code List. My '71's dealer, Schuman Carriage Co., Ltd, started as a carriage maker in 1893, Model Ts in '04, some brands that no longer exist along with a couple location changes. By '60, a GM dealer with Buick and Cadillac (I don't count Opel). By '64 they had 200 employees. GM named Schuman top new/used car dealer in '68. By 21st century, they had taken on GMC, Hummer, Subaru, and NAPA parts. Dealership closed in Nov '04 as oldest dealer in Hawai'i and one of oldest in nation...
Sweet, I was able to find the dealership where my Buick was ordered also. I purchased it about 60 miles from the dealership. I found pictures of the dealership as it currently look, but nothing from 1969. I found mentioning of it in a yearbook from the late 60s. It was owens buick for only a couple years then it went away. His name is mentioned in small print under another guy’s name, so maybe he was a partner then took over from 69-70.
Twin City Motors is what came on my Sloan report. Newspaper ads from 1970 referred to ....Motors, but the dealership sign was ....Buick.
...dealer will sometimes have ad in high school yearbook because they provided driver ed cars. I've also found postcards/old ads on eBay and in period local newspapers...
...sounds like name change was current to '70, and dealer either hadn't changed sign yet, or maybe left it alone as long as possible to capitalize on old name recognition...
