<prompt> Human: I dont know anything about cars and I just got a job offer for a yearly salary at 30,498. Im planning on buying a car. I wanted to get a convertible, either a Mazda Miata MX-5 or Ford Mustang and I wanted to know if I can afford these cars or how I can determine if I can afford a car. EDIT: 600 in rent. 100 ish on groceries. 80 on bus passI dont have much savings because I am working at 10 an hour. And I never have a spare to save. Im hoping to start budgeting once I get the new job.  <response>: How much money do you have saved? What are your monthly expenses?And lets get this out here right now: you cant afford a 30k car on 30k a year of income.
