Set Your Budget
Use our car affordability calculator. Keep total car costs (payment, insurance, gas, maintenance) under 15-20% of take-home pay.
Get Pre-Approved
Check rates at your bank or credit union before the dealership. This gives you negotiating power.
Research Your Options
Compare new vs. used. A 2-3 year old certified pre-owned car avoids the steepest depreciation.
Consider Total Cost of Ownership
Don't just look at the sticker price. Factor in insurance, fuel, maintenance, and depreciation.
Lease vs. Buy Decision
Leasing = lower payments, always new car. Buying = higher payments, but you own it and build equity.
Negotiate the Price
Focus on the total out-the-door price, not just the monthly payment. Get quotes from multiple dealers.
