Knowledge Is Your Greatest Advantage.

The out-the-door (OTD) price is the total you pay to drive the car away: the vehicle's selling price plus dealer fees, sales tax, tag, title, registration, and any products you add.

In Florida, that includes the 6% state sales tax plus any county discretionary surtax, which applies to the first $5,000 of the price. Always ask for the OTD number in writing. It's the only number that lets you compare two dealerships fairly.

APR is the yearly cost of borrowing, including interest and certain finance charges. Your credit history, the loan term, the vehicle's age, and your down payment all affect it.

A longer term lowers the monthly payment but usually raises the total interest you pay. Compare loans on total cost, and ask what APR and term a quoted payment is based on.

If you owe more on your current car than it's worth, the difference is negative equity. Dealers can roll it into your new loan, which means you're paying off the old car inside the new one.

Get your payoff amount from your lender and an independent value estimate before you shop. Then negotiate the trade-in separately from the new car's price.

A down payment reduces how much you borrow, which lowers your payment and total interest, and can help with approval if your credit is still building.

It also reduces the chance of owing more than the car is worth early in the loan. Keep an emergency cushion; don't empty your savings to make the down payment bigger.

New cars come with full warranties and sometimes promotional rates, but lose value fastest in the first few years. Used cars cost less up front, and a certified pre-owned car adds an inspection and extended coverage for a premium.

The right choice depends on how long you'll keep it, how much you drive, and the financing you qualify for on each.

A hard inquiry happens when a lender checks your credit for an application. When a dealership sends your application to several lenders, each can appear on your report.

Most scoring models count multiple auto-loan inquiries within a short window as one for scoring purposes, typically 14 to 45 days depending on the model. The individual inquiries may still be listed. Checking your own credit is a soft inquiry and doesn't affect your score.

The payment is only part of the cost. Insurance in South Florida can be significant and varies a lot by vehicle and ZIP code, so get a quote on the exact model before you commit.

Add fuel, maintenance, tires, and registration renewals to see what the car really costs each month. Lenders usually require full coverage on a financed vehicle.

Florida dealers commonly charge a dealer or administrative fee, which they're required to disclose. Government fees like tax, title, and registration are set by the state; dealer fees and add-ons are set by the dealer.

Optional products such as service contracts, GAP, and protection packages should be offered, priced, and explained individually. You can decline them.
