Mobility scooter

I currently rent my scooter which cuts into my budget and continues to do so , my scooter is a good model and reliable the only issues that could happen are tyres and battery which are easy to replace. I would like to keep my scooter instead of having to send it back and get a new scooter of which I have to do every three years on the motorbility benefit  system.
As you can see my scooter is in good condition for a three year old scooter. I’m not used to asking for money but if people could help me get the money that would help a awful lot then I can use my mobility component to hire out other mobility appliances and a good quality wheelchair for use when I can’t use my scooter.
