My credit score is fair (low 600) my cosigner's credit score is 850+ will I get approved?

82 months is almost 7 years, which is ridiculous (you do understand that even if you sell the car you're still on the hook to pay it off...or if the car breaks down). I wrote a white paper 4 years ago on how the auto industry is making the same mistakes that the housing industry made 8 years ago (making questionable loans to people with bad credit and completely screwing people over with long-term loans at high interest rates).

Without knowing who you're going through for financing it's hard to say. If the interest rate is more than 6%, walk away. If it's 10% or more, run away. Ask them what is the APR (interest rate) on the financing. You're getting screwed over by a loan that, statistically speaking, will cause harm to your credit and you'll end up paying far more for that car than it's actually worth.

You're financing a cheap car for 7 years???? Are you crazy?

probably not approved

82 months is insane. Your cosigners income and other debts might come into play but your income is a big problem.

Most car dealerships start at $1500 for a minimum deposit.
