Shoprider Mobility Scooter

Red Shoprider Cobra Deluxe 13 year old mobility scooter. It is operational but has 1 flat front tire. I was quoted $150 for a scooter shop to replace it but, if you're capable, it would be simple to change it yourself... I think =). Powered by Pihsiang. This unit has some cosmetic damage on the front bumper area, a small hole in an area of the foot board that affects nothing, and a tear in the fabric on the side of the back of the seat. It is otherwise in good condition. The seat is comfortable, adjustable and supportive. The batteries are every bit as good as my brand new scooter, which I only got because I mistakenly thought this scooter couldn't be put in neutral if the battery ever died while I was out... I purchased the exact same scooter because I like it so much! I am moving and I don't want to drag a second scooter with me if I don't have to. Karrot Vision says it's worth $450 but because it needs a tire and is fully charged but has no charger (less than $50 on Amazon), I would like to get $210 for it if possible, I could really use the cash for my move =).
