loan- car loan (single parents)

Do u know or can recommend one thats possible for single parent with no work. It is difficult atm and with parenting plan now in place i need to do drop and pick to lo's daddy which is 2 hours away. It can be done by bus buy take 12hrs altogether but with own car it can save half of that time. I have $2000 save but have test drives cars for sale with that amount isnt reliable enough. Im only looking at $3k- $4k loan to make sure i get reliable car. Anyone got a loan with single parenting?
