$4,800 every 6 months is only $800/month. The OP pays $500/mo on insurance, let’s say $100 on gas a month, that’s only $200/month payment on the loan for an old used car. Car ownership is expensive, but it’s probably more common for the car payment to be $500/month and insurance to be $200/month. This doesn’t even factor maintenance
