Mx5 Koni sport/ H&R springs & Marhua top mounts

I am selling a set of Koni sport shocks with H&R springs and Marhua top mounts, which have only been driven for 300 km (and not even hard). I am selling them because I am parting out my car. Together, these have a new value of over €1200, and I am asking €900. Please do not offer absurd prices. For the brief 300 km I drove on them, they performed fantastically, providing both comfort and firmness when needed. I also have a friend who had these, and we drove hard with his car, and they felt much better than a set of coilovers at the same price point.
