Back in the day, it was common practice when you purchased a new automobile that the Buick car dealership you bought it from would include a key fob.
This was a free gift for the buyer, and basically free advertising for the Buick dealer (a subtle reminder for customers to come back to the same dealer when they’re ready for a new automobile).
When current vehicle owners sold their autos for whatever reason, they usually would pass on these key chains to the new buyers.
These advertising key rings are part of the history of the specific Buick Turbo Regal that is being passed on.
They are a neat accessory, kind of like an original license plate frame from the Buick Dealership.
Ebay has a ton of assorted Buick Dealer keychains for sale constantly, so it’s very possible you can acquire one from the original dealership where your car was first sold from.
Here’s a peek at a few various Buick Dealer Key Fobs.
