Tommy Nix Auto Group is a dealership chain with multiple locations across the Southeast
Tommy Nix Auto Group operates several car dealerships in states including Georgia, Florida, and South Carolina. The group sells both new and used vehicles and offers financing through their own lending department. Like any dealership, they handle trade-ins, warranty options, and loan paperwork on-site.
Before visiting or working with any dealership, it helps to understand how the sales process works, what documents you'll need, and what questions to ask. This guide covers the practical steps involved in buying a car from a dealership and what to watch for at each stage.
Key Takeaways
- Dealerships like Tommy Nix make money on the sale price, financing terms, and add-on products like warranties and gap insurance.
- You should know your credit score and get pre-approved financing from a bank or credit union before arriving, so you can compare the dealership's loan offer to an outside offer.
- The purchase agreement, loan documents, and warranty terms are separate contracts — read each one before signing and ask what each covers.
- Trade-in value, interest rate, and loan term are the three numbers most worth negotiating, because small changes in any of them affect your total cost significantly.
How dealership financing works and why it matters to your total cost
When you finance a car through a dealership, the dealership does not usually lend you the money directly. Instead, they arrange a loan through a bank, credit union, or finance company, and that lender pays the dealership the full purchase price. You then repay the lender, not the dealership. The dealership earns money by marking up the interest rate — they negotiate a rate with the lender, then offer you a higher rate and keep the difference.
This markup is called the dealer reserve or dealer participation. A lender might approve you at 6 percent, but the dealership offers you 6.5 percent and keeps 0.5 percent of the interest you pay over the life of the loan. On a $25,000 loan over five years, that difference adds up to hundreds of dollars.
The reason this matters is that you have leverage. If you bring a pre-approval letter from your own bank or credit union showing you can borrow at 6 percent, the dealership knows they cannot mark up the rate as much. You can tell them: "I have an outside offer at 6 percent. Can you beat it?" This forces them to choose between a smaller markup or losing the sale.
What to do before you visit the dealership
Check your credit score through a free service like AnnualCreditReport.com or through your bank's website. You do not need to pay for a credit score — the free versions are accurate enough for this purpose. Knowing your score tells you what interest rate range you should expect, and it alerts you to any errors on your report that could raise your rate.
Next, contact at least two lenders — a bank, a credit union, or an online lender — and ask for a pre-approval. Pre-approval means the lender has reviewed your credit and income and will lend you up to a certain amount at a certain rate. The pre-approval is good for 30 to 60 days and does not lock you into borrowing from that lender, but it gives you a concrete number to compare against the dealership's offer. Bring the pre-approval letter with you.
Finally, research the specific vehicle you want. Use resources like Kelley Blue Book or NADA Guides to find the fair market value for that make, model, year, and condition in your area. Write down the price range. This is your anchor when negotiating the purchase price.
The documents you will sign and what each one means
The dealership will present you with several separate documents. The purchase agreement or sales contract states the vehicle, the price, any trade-in, and the down payment. This is the contract between you and the dealership for the sale itself.
The loan agreement or promissory note is a separate contract between you and the lender. It states the loan amount, the interest rate, the monthly payment, and the number of months you have to repay. Read the interest rate carefully — this is where the dealership's markup appears.
The warranty or service contract is optional and is a third separate contract. It covers repairs after the manufacturer's warranty ends. Dealerships often try to add this without asking, so confirm whether it is included in the price or offered separately. If offered separately, you can decline it or negotiate the price down.
Gap insurance is also optional. It covers the difference between what you owe on the loan and what the car is worth if the car is totaled before the loan is paid off. It is useful if you are putting down less than 20 percent, but it is not required by law and you can buy it from an insurance company instead of the dealership.
Three numbers worth negotiating and how to approach each one
The purchase price is the starting point. Use the fair market value you researched before arriving. If the dealership's asking price is above that range, ask them to come down. If it is within range, you can still negotiate — dealerships expect it. A typical opening move is to offer 5 to 10 percent below asking and let them counter.
The trade-in value is the second number. The dealership will appraise your current car and offer you a value. That value is not fixed — it is a negotiation. If you disagree with their appraisal, you can ask them to explain it, or you can get a second appraisal from a different dealership or from a service like Edmunds or Kelley Blue Book. Use that second opinion as leverage.
The interest rate is the third number. This is where your pre-approval letter is most useful. Tell the dealership your outside rate and ask them to match or beat it. They may not be able to — some lenders have stricter terms than others — but you will not know unless you ask. Even a 0.5 percent difference saves you money over the life of the loan.
What happens after you sign and what to watch for
After you sign the purchase agreement and loan documents, the dealership will give you a copy of each. Keep these in a safe place. The lender will mail you additional copies and will set up your payment schedule — usually automatic payments from your bank account.
Some dealerships use a practice called spot delivery or yo-yo sales. You drive the car home the same day, but the dealership tells you the financing is not final and asks you to return if the lender does not approve the loan. This is legal in some states and illegal in others. If this happens, contact your state's attorney general or consumer protection office to find out your rights. In most cases, if you have signed the purchase agreement, the car is yours even if the financing falls through.
Review your loan documents carefully when they arrive. Confirm that the interest rate, loan term, and monthly payment match what you agreed to at the dealership. If they do not, contact the lender when ready and ask for an explanation.
How to handle problems after the purchase
If you discover a mechanical problem with the car shortly after purchase, check your purchase agreement to see whether the dealership offered any warranty or may provide. Many used car sales are sold "as-is," meaning the dealership makes no promises about the car's condition. If the agreement says "as-is," your options are limited, but you may still have rights under your state's lemon law or consumer protection statutes — contact your state's attorney general's office to learn what applies to you.
If you believe you were misled about the car's condition or history, or if the dealership misrepresented the financing terms, document everything and file a complaint with your state's attorney general and with the Federal Trade Commission at ReportFraud.ftc.gov. These complaints do not reverse a sale, but they create a record and may trigger an investigation if the dealership has a pattern of complaints.
Frequently Asked Questions
Can I return a car to a dealership if I change my mind?
Most dealerships do not have a return policy — once you sign the purchase agreement, the sale is final. Some dealerships offer a short return window (usually three days or fewer), but this is voluntary and varies by dealership and state. Check your purchase agreement to see if one is mentioned. If you are unhappy with the purchase, your only recourse is if the dealership broke the law or misrepresented the car.
What is the difference between certified pre-owned and used?
Certified pre-owned (CPO) vehicles have been inspected and reconditioned by the dealership and usually come with a longer warranty than regular used cars. They cost more than non-certified used cars but less than new. The warranty is the main benefit — read what it covers before deciding whether the extra cost is worth it for you.
Should I buy an extended warranty from the dealership?
Extended warranties are profitable for dealerships, which means they are priced high. Before buying one, research the reliability ratings for that vehicle and model year using Consumer Reports or J.D. Power. If the vehicle has a strong reliability record, an extended warranty may not be necessary. If you do want one, you can often buy it from a third-party provider for less than the dealership charges.
What if the dealership says the interest rate changed after I signed?
The interest rate on your loan agreement should not change after you sign, unless you agreed in writing to a change. If the dealership claims the lender rejected the rate and a new rate was approved, ask for written documentation from the lender explaining why. Compare the new rate to your pre-approval offers and decide whether to accept it or walk away.
How do I know if I am getting a fair price on my trade-in?
Get an appraisal from at least one other source — another dealership, a used car buyer like Carmax, or an online valuation tool like Edmunds or Kelley Blue Book. Compare the offers. If the dealership's offer is significantly lower, ask them why. They may point out damage or mileage you did not account for, or they may straightforward be offering less because they can. Use the other appraisals as negotiating points.
