This is a Combi Joytrip Advance in Navy. I bought it new in 2023 and have been using it for about two years. It cost a little over 40,000 yen at the time. There are scratches on the seat, but otherwise, there don't seem to be any noticeable scratches or stains. I feel like the seating area is slightly worn (no fraying). It has been home-cleaned. Also, there are no pets or smoking. I've used it for two years, but I only use the car about once a month, so it hasn't been used excessively. *No instruction manual --- Combi Joytrip Advance ISOFIX Eggshock SA Navy (NB) Compliant with the new safety standard R129, which incorporates new standards to improve safety.
