First, let's suppose you net $350 a week and living at your parents rent-free and saved $10,000 over 7 months not spending on anything.
$30,000 loan on 5 years at an unfavorable 7% APR is close to $600/month car payment
Car Insurance is full coverage required probably about $1800 a year as minimum so another $150 a month
Getting a car and not driving it is really silly, so let's say 6000 miles a year as a low use, at 500 miles a month at say $0.15 fuel and maintenance not counting depreciation for another $75
$825/month out of the $1460
Are you buying a car, or being a slave to a car?
Do you expect to live at home another 5 years?
A minimum wage type job at full time is not a career. It is AFJ otherwise known as Any F'cking Job, and the car you drive, if you can get one at all, is AFC, Any F'cking Car.
If you can buy a cheap car for cash, you can put on minimum liability insurance and have no payments.
Your goal is finding a car and maybe learning about basic car maintenance and repair.
You also consider that you really need a career or in the long run, life will be crap.
Consider the nearest university and graduating students dumping functional cars cheap.
You build your credit rating with a secured credit card and learning how to use it to raise your credit score until you are approvable for an unsecured credit card.
Until you have a decent salary, you can't afford a decent car.
Don't measure your worth as a person by the car you drive. A good friend had a decent job and bought a $30,000 car, lost his job, and the car was repossessed a couple of months later. He measured life's success by a car and apartment and he lost both.
Per comment - a minimum wage job (or close to it) is not a career, until and unless you advance in it.
College is a prerequisite to a career so have your goal proper. Many college students don't find a good job.
Your options of getting around are generally private car, public transport, or Uber/Lyft.
Consider that Uber/Lyft is sometimes cheaper than owning a car.
Judge yourself by your integrity and wisdom and those things you learn in life.
I'd rather know a happy funny honest person than one driving a Mazerati.
A car is a thing. It is a possession. They break, get lost, stolen, taken away for other reasons, and if not, depreciate in value.
When ready for the car of your dreams, you'll know it because buying and owning it won't be a pressure on life.
Cost of ownership of a car including depreciation, insurance, gas, maintenance, registration and fees and tolls should not exceed about 10% of gross pay. Anything higher means giving up things.
If grossing $400, you really can only afford $40 a week, which today means AFC
If earning median USA $38K/year, and that's only $76/week
$40,000 cars are for people earning around $100K a year
