Another round of some key chains from assorted Buick Automobile Dealerships in the US of A.
Most of these vintage key rings were made out of leather that were stamped into or embossed containing the car dealers names, locations, and a phone number.
Sometimes they had a various Buick logo on them.
Other styles were made from plastic or rubber.
If you bought your Turbo Regal new, perhaps the car lot you bought it from gave you something similar to these.
If you purchased your Turbo Buick used, then maybe the original owner passed on one of these neat key fobs with the purchase of the car.
If neither applies, there’s plenty of these types for sale on ebay and elsewhere, usually for less than 20 bucks.
