to help get a cash car, and things we need

my name is Priscilla im a single mother of 3 kids. I've been threw so much in the last few years but I've always stayed strong for my kids no matter how hard things got. I just moved back to Houston because Jabari is going to be having more surgeries to release his arms leg neck so he can be able to walk crawl ect. my car's engine just went out it was knocking then end up locking up it was going to cost more then the car's worth to get another engine. I don't need anything fancy just something reliable to get me from point a to b.
