$450 · NEW maxi cosi adorra stroller

We got a new Stroller through our warranty, as ours got broken, we are keeping it in the box. Is still not open. We are selling it cause we are expecting a second baby so we rather buy a double stroller with the money we get from it. The colour is nomad green, found it for 520$ + tax as cheapest option right now so I am asking 450$. Xposted
