Loan balance over time

The 20/4/10 rule: put at least 20% down, finance for no more than 4 years, and keep total car costs (payment, insurance, gas) under 10% of your gross income. If the only way to afford the car is stretching to 72 or 84 months, it's the car that's too expensive — not the loan that's too short.
