Preston Automotive Group is a car dealership network, not a financial program
Preston Automotive Group operates multiple car dealerships across the United States under different brand names. If you arrived here looking for information about buying a car from one of their locations, financing through them, or understanding their warranty and service policies, this guide explains how to approach that purchase and what to watch for.
Preston locations sell new and used vehicles and offer in-house financing options. Like any dealership, they make money on the sale price, trade-in value, financing terms, and extended service contracts. Understanding how each of these works protects you from overpaying or locking into unfavorable terms.
Key Takeaways
- Preston Automotive Group operates multiple dealerships under different names, so confirm you are at an actual Preston location before negotiating.
- Dealership financing often carries higher interest rates than bank or credit union loans you could bring with you, so compare offers before signing.
- Extended warranties and service contracts sold at the dealership are optional add-ons with real costs — read the terms and consider whether you need them.
- Your right to cancel a purchase or financing agreement depends on your state's laws and the specific contract language, not on dealership policy alone.
How dealership financing works and why your rate matters
When you finance a car through Preston Automotive Group, the dealership arranges the loan with a bank or finance company on your behalf. The dealership does not lend you the money directly — they act as a middleman. This means the dealership can mark up the interest rate they offer you above what the lender actually charges them, and that markup is how they profit from the financing.
Your interest rate depends on your credit score, credit history, down payment size, and the length of the loan. A higher credit score usually means a lower rate. However, the rate the dealership quotes you may be higher than what you could get from your own bank or credit union. Before you walk into a Preston location, contact your bank or a local credit union and ask what rate they would offer you for a car loan. Bring that offer with you — dealerships often will match or beat an outside offer to close the sale.
The financing paperwork you sign is a contract with the lender, not with Preston. Once you sign, the dealership sells that contract to the lender and receives their money. This means if you later have a problem with the loan terms, you deal with the lender, not the dealership.
Trade-in value and how it affects your final price
If you trade in a vehicle, the dealership will appraise it and offer you a value. That value is negotiable, just like the price of the car you are buying. Many people focus only on the new car's price and overlook the trade-in value, but the two are connected — a lower trade-in offer means you pay more out of pocket even if the new car's sticker price stays the same.
Before you visit Preston, research your trade-in vehicle's value using Kelley Blue Book, NADA Guides, or Edmunds. These sites ask for your vehicle's year, make, model, mileage, and condition, and show you a range of fair market values. Bring that information with you. If the dealership's offer is significantly lower than what you found, ask them to explain the difference — they may have spotted damage or mechanical issues you missed, or they may straightforward be offering less than fair value.
The trade-in value also affects your loan amount. If you owe money on your current vehicle, the dealership will pay off that loan from your trade-in value. If the trade-in value is less than what you owe, you are "upside down" and will need to pay the difference out of pocket or roll it into the new loan, which increases your monthly payment.
Extended warranties and service contracts: what they cover and what they cost
Preston dealerships sell extended warranties and service contracts as add-ons after you have agreed on the car's price and financing. These contracts promise to cover certain repairs after the manufacturer's warranty expires. They sound appealing, but they are optional, they cost real money, and they come with limits and exclusions.
Before you agree to buy one, ask the dealership for the written contract and read it carefully. Look for what is covered (engine, transmission, electrical, suspension, etc.), what is not covered (wear items like brakes and tires, routine maintenance, damage from accidents), how long it lasts, how many miles it covers, and what you pay out of pocket when you use it (called a deductible). A $2,000 warranty with a $500 deductible and a list of exclusions as long as your arm may not be worth the cost.
You can also buy extended warranties from third-party companies after you leave the dealership, sometimes at a lower price. If you decide you want coverage, compare the dealership's offer to what you can find elsewhere before you sign.
Your rights if you want to cancel or return the vehicle
Many states have a "cooling-off period" that gives you a short window — usually three days — to cancel a car purchase and get your money back. However, the rules vary by state, and not all states have this protection. Some states allow it only for private sales, not dealership sales. Others have no cooling-off period at all.
Check your state's consumer protection laws or contact your state's Attorney General's office to find out what applies to you. If your state does have a cooling-off period, the dealership is required to tell you about it in writing at the time of sale. If they do not mention it, that does not erase your rights — it just means they failed to inform you.
If you discover a mechanical problem with the vehicle after you drive it home, your recourse depends on whether the car is new or used and what your state's lemon law says. New cars are usually covered by the manufacturer's warranty and sometimes by state lemon laws if they have repeated defects. Used cars have fewer protections, though some states require dealerships to disclose known defects or sell used cars "as-is."
How to negotiate the best deal at Preston Automotive Group
Everything at a dealership is negotiable except the manufacturer's suggested retail price (MSRP), which is just a starting point. The dealership's profit comes from the gap between what they paid for the car and what you pay them, plus financing markup, trade-in value, and add-on sales.
Come prepared: know the fair market value of the car you want using Edmunds, Kelley Blue Book, or TrueCar; know your trade-in vehicle's value; bring a pre-approved loan offer from your bank or credit union; and decide in advance which add-ons (if any) you actually want. Write down your target price for the car, your target trade-in value, and your target interest rate. Use these numbers as anchors during negotiation.
Negotiate one thing at a time. Agree on the car's price first, then the trade-in value, then the financing terms, then any add-ons. This prevents the dealership from bundling everything together and making it hard to see where your money is going. If you feel pressured or confused, take a break and walk away. You can always come back, and the dealership knows that.
Red flags and common dealership practices to watch for
Some dealership practices are legal but designed to make you spend more money. Spot them and you can protect yourself. One common tactic is "yo-yo" sales, where you drive the car home and the dealership later calls saying the financing fell through and you need to come back and sign new paperwork with a higher interest rate. This is legal in some states and illegal in others — know your state's rules.
Another tactic is bundling add-ons into the financing so you do not see the separate cost. For example, a $2,000 extended warranty gets rolled into your loan, and you end up paying $2,500 or more for it over five years because of interest. Always ask for the cost of each add-on separately and decide whether you want it before it goes into the contract.
Pressure to decide quickly is also common. Dealerships use phrases like "this price is only good today" or "another customer is interested in this car" to rush you. In reality, similar cars are available elsewhere, and most dealerships will negotiate with you tomorrow if you walk out today. Take your time and make decisions based on numbers, not pressure.
Frequently Asked Questions
Can I return a car to Preston Automotive Group after I buy it?
That depends on your state's laws and the contract you signed. Some states have a three-day cooling-off period for car purchases, but not all do. Check your state's consumer protection laws or contact your state's Attorney General's office. If your state has this protection, the dealership must tell you about it in writing at the time of sale.
What if the car I bought from Preston has a problem after a few weeks?
If the car is new, the manufacturer's warranty covers defects for a set period (usually three years or 36,000 miles). If the car is used, it may be sold "as-is" with no warranty, or it may come with a limited dealership warranty. Check your paperwork to see what coverage you have. Some states also have lemon laws that protect buyers of new cars with repeated defects.
Should I buy the extended warranty the dealership is offering?
Read the contract carefully first. Look at what is covered, what is not, how long it lasts, the mileage limit, and your out-of-pocket cost per repair. Compare the dealership's price to third-party warranty companies. If the coverage is narrow or the cost is high, you may be better off saving that money and paying for repairs as they come up.
What if the dealership's financing offer is much higher than my bank's offer?
Bring your bank's offer to the dealership and ask them to match it. Many dealerships will do this to close the sale. If they refuse, you can decline their financing and use your bank's loan instead. You are not obligated to finance through the dealership.
How do I know if the trade-in value they offered is fair?
Research your vehicle's value on Kelley Blue Book, NADA Guides, or Edmunds before you visit. These sites show you a range based on condition, mileage, and market demand. If the dealership's offer is significantly lower, ask them to explain why. They may have spotted damage or mechanical issues, or they may straightforward be offering less than fair value.
