hello.. I’m just trying desperately to find and purchase the 1/18 1970 GSX in Saturn Yellow that was done for the GS Collectibles Club byErtl. It came with a larger Yellow certificate. I know there’s a lot of versions done in this color but the again the one I’m looking for is the higher detailed version that had silver trim highlights around windows and wheel well lips and hood scoops as well as rocker panel is trimmed in silver and black. They did a clean version and a dirty version. I’m looking for the clean version one. Please please let me know if you have one and price Thanks
