$200 · britax marathon car seat in cowmooflage

Used Britax marathon carseat. Manufactured in 2014 (in pictures) will expire in 2024 Rear and forward facing options. My daughter has grown out of it. No accidents ever. Only owner. Hasn't been used in a year, stored inside. Price is 200, but I am open to offers or trades. I have contacted Britax directly and confirmed the expiration date and that the car seat still complies with safety regulations.
