"High lux polish" was a factory option. My car has them but i don't care for the finish either. The nice thing is that you can put any finish over high polish and then strip it off if you ever decide to change. I'll be changing the finish or buying new wheels soon. High lux is often confused for chrome. There are some chrome knock-offs out there.I didnt realize they came in Chrome. Cant say I have ever seen OEM in Chrome, but I could be wrong.
Off course, the are all over Ebay. Find a reputable seller with a new set and you should be good to go.
