I have a 2002 is300 and the car parts for this car are becoming extinct day by day lol. I am looking for a decent roof spoiler for my is. I am really trying to avoid the ones off ebay, but finding a real company that still makes parts for this car is becoming almost impossible. Could I order one from a toyota/lexus dealership ? Any tips?

Toyota never made an OEM roof spoiler for the **e10 series. You can look for a UGO roof spoiler (but i think i remember its been discontinued), a Lsportline spoiler, or a Hipposleek (real JDM ****) spoiler.
