If you're old enough to remember when the now-defunct Vidmar Buick car dealership sold Opel cars -- or you know that Opel is a German-based car line no longer sold in this country -- this eBay item up for auction may be for you.
It's a key ring from 1970s advertising the old Joliet dealership, featuring "Joliet, Ill." and an area-code free phone number.
The auction starting price is $6.99, with $2.90 for shipping. Bidding ends Feb. 3.
Here's how the seller describes the item (mistakenly writing Oldsmobile instead Buick and misspelling Opel):

(Opel cars, by the way, stopped being sold in the United States in 1975 but are still made and sold mostly in Europe. Buick retains a link to the company and some Buick models are based on Opel designs. For example, the Buick Regal is "rebadged" Opel Insignia.)
