My wife has a 2018 Q50S with every option, from what the Stealership told me. No dealer installed carbon accessory package. My issue is what color rear spoiler do I put on the deck lid ? Stick with the factory K23 Liquid Platinum color or match the color around the rear diffuser,front spoiler and driving light dark metalic finish or pop the extra $$ for a carbon fiber rear spoiler. Any opinions would be appreciated. Or photos of the K23 color. I will probably use the OEM style or similar spoiler.
