Those are probably from a 1995 model, the only year in which 8 hole wheels were polished and clearcoated. Prior to that they had always been silver painted and clearcoated. The polished / clearcoated wheels often don't look very good - not really as durable as painted / clearcoated. You can of course strip off the clearcoat and either polish again or paint, and clearcoat again. Polished wheels without clearcoat don't seem to last long either - they dull rather quickly.
