Help. Need a Car

Last Tuesday night my car was broken into. They broke my sunroof and window and tore out all the dashboard and electrical. It could be over $1000 to repair. I’ve decided to just try to get a used reliable car to replace my 20 year old Volvo. I’m 68 and disabled. I just don’t have the funds to do this. My mechanic has a used car in great condition for $3500. I’d need to register and insure it too so that needs funding too. Please help if you can. This is the hardest thing to ask for help but I really need help on this. I help care for my dad 93 and a car is essential.
