Know What You're Walking Into
Quick reads on the most common things dealers do — so you know what to expect.
Your Interest Rate Can Be Marked Up
The lender gives the dealer a base rate. The dealer can charge you more and keep the difference. Getting pre-approved from your own bank gives you a number to compare against.
Not All Fees Are Required
Taxes, title, and registration are real. But fees like "market adjustment," "dealer prep," or "admin fee" are optional — and can often be removed if you ask.
The Finance Office Is a Second Sales Pitch
Once you agree on a price, they'll offer warranties, protection plans, and insurance — often priced much higher than what they cost the dealer. You can say no to all of it.
Handle One Number at a Time
Dealers like to mix your price, trade-in, and monthly payment together. Focus on the vehicle price first. Then talk financing. Then trade-in. Keeping them separate makes it easier to spot a bad deal.
