You can go to the Shatin showroom. A few days ago, there is still a black Dynamic version equipped with fog light and rear wing. I am pretty sure you can get a rear spoiler but I do not know how much. I will go to the showroom again today. Do you want me to ask how much is the rear spoiler for you?
