The only option my base 84 came with other than a basic radio. Pretty sure the PO's never tried to clean them. Once I refurbished the car, I scrubbed and scrubbed and then polished the clear coat off the lips of the rim to give them a little more pizzaz. I hate 'em, but they are nostalgia cool! Keep them, they are not very common. Most buyers likely realized how tedious they are to keep clean, so didn't buy them.
