I lost a hubcap on the Buick Century a couple weeks ago. It was on my way to Terre Haute. I have no idea when or where, and I don't understand how because those things are a bugger to get off. But I did. It was the rear passenger side.
Friday (7.12.13) I finally just bought a set of hubcaps at Walmart for $20. They are really cheap and I know they won't stay on forever, but I was there getting a prescription anyway and thought 'what the heck.' So I put two of the new ones on the passenger side and left the originals on the drivers side.
