Mom of 2 seeking cheap car - $500

Hellooo so long story short, momma needs a car for her and her two toddler aged kiddos! Really just looking for someone kind with a running car they are trying to get rid of for cheap! I'm a young mom finally trying to work towards independence, so I can hopefully start taking steps towards getting my babies from our ~unhealthy~ living situation.
first step being a car, so I no longer need to rely on transportation from unreliable family members.
A sedan size would be preferred! The budget is 200-500$, and id be more then happy to work out a payment plan! Pls no totally trashed lemons is all I ask, just need a point a to b vehicle 🥺👏 it would be life changing, tha ks for taking the time to read! ♥
