Graco Mirage travel system including isofix base for car seat ?

Graco travel system in very good condition, only used for just over 5 months. Paid 150 for it while pregnant last year. Including 2 rain covers, 1 never been used and still in packaging. We will also include Graco Isofix car seat base, which we bought separately for over 50 last year, but goes with the car seat. We have manuals/ instructions too. Travel system is fully assembled.
