The aftermarket vendors ,Mid America Design, etc. all offer chromed wheels for around $700 plus your old wheels in exchange.
Other options, but with a lower shine, are to have the clear coat striped and the wheels polished. Check with any local speed shop or in the yellow pages under wheels or tires.
A third options is to do it your self. The clear coat will come off with thinner and 0000 steel wool and elbow grease. Paint stripper will work but it is best if you remove the tires. Then the wheels can be buffed to a shine. You can get wheel polish and wax for wheels at auto supply stores.
