Step 1: Set Your Budget
Before looking at cars, know your budget. Many first-time buyers overextend themselves and become "car poor."

Keep total monthly car costs (payment + insurance + gas) under 15% of your take-home pay.

Avoid "Car Poor" Trap
Don't let car payments consume your income. You still need money for housing, food, savings, and fun.

Frequently Asked Questions
What credit score do I need to buy my first car?
You can get approved with any credit score, but rates vary significantly. Excellent credit (750+) gets 4-6% APR, good credit (700-749) gets 6-8%, fair credit (650-699) gets 9-13%, and poor credit (below 650) may see 15-25% APR. If your score is low, consider building credit 6-12 months before buying to save thousands in interest.
Should I buy new or used for my first car?
Used cars (2-4 years old) usually make the best first cars. They cost 30-40% less than new, have lower insurance rates, and have already taken the biggest depreciation hit. You can upgrade to new later when you have more experience and income.
How much should I spend on my first car?
Keep total car costs (payment + insurance + gas) under 15% of your monthly take-home pay. For first-time buyers, $12,000-$20,000 often hits the sweet spot of reliability without overextending. Focus on a practical, reliable vehicle rather than something flashy.
