help me and my family buy my new van

My name is Seth and i have cerebral palsy I have been living on my own for 8 years. Before I moved out of my grandparents house my grandmother bought me a 2005 Dodge Grand Caravan with a wheelchair ramp. Last week the door with the ramp fell off. The bill to repair it is more than $2000. It is absurd to put in money into an almost 20 year old van! my parents have saved some money to put towards a new used van but its not nearly enough to cover the cost. So thats why im here. Any help will be appreciated
