Kolcraft Contour With Car Sear Adaptor

I have a Kolcraft Contour in good condition with its Carseat adaptor. Reason for selling is that I'm in search of a lightweight stroller I can be able to lift up and down stairs and on and of buses since I rely 100% on MTA transportation. Plus it is taking up to much space in my room. Below are pictures but not actual pictures of the stroller . One picture shows u what the stroller looks like with the carseat on the adapter and what the stroller looks like normally. Almost everything on the stroller is nearly detachable for parent convenience...and the basket on the bottom is extra large for storage.
