We know that you have high expectations, and as a car dealer we enjoy the challenge of meeting and exceeding those standards each and every time. Allow us to demonstrate our commitment to excellence!

We know you have many options when it comes to choosing a dealer. Here's a little about us:

At Key Auto Group, we are proud to be leading change in the auto business, as we understand that today's consumers demand and deserve quality service, quality products, and a hassle-free shopping experience.

To begin, every new Key Auto vehicle is pre-discounted to reflect available rebates and dealer incentives. These vehicles all qualify for our industry-leading $1000 price match guarantee. Additionally, each Key Auto Certified Pre-owned Vehicle is priced to reflect its market value, and our most competitive price is displayed right online for the world to see. This completely eliminates the hassles from car buying, and makes it easy to do business here.

All Key Auto Certified Pre-owned vehicles undergo a rigorous 70 Point Vehicle Inspection that includes tires, brakes, engine, transmission, all power options and electrical items. Each Certified Vehicle must at least double state inspection requirements in order to be placed on the lot for sale. After the inspection, our vehicles receive a state-of-the-art detail job that makes them look, feel and smell brand new. Finally, each Certified Vehicle receives a warranty depending on year and mileage. This process results in a finished product that consistently exceeds our customers' expectations.

At Key Auto Group, we provide our customers with four separate facilities full of new and pre-owned inventory. All our locations feature fully-staffed service departments that service all makes and models. You will come to love our service departments, as you'll receive free New Hampshire State Inspections for the life of your vehicle.

We take pride in our careers and we never stop finding ways to improve our customer relationships. I will show you some examples of people who have bought here, loved it, and will never buy anywhere else.

Our service departments are completely focused on creating a perfect finished product for our customers. This is why we do full certifications to all of our Portsmouth NH used cars and trucks  with fewer than 80K and less than 5 years old.

Interest Rate Information
Interest rates are extremely important to many car buyers. The interest rate you get on your loan can often influence whether or not the monthly payment fits within your budget.

Although it is impossible to predict an exact interest rate without pricing and credit information, you will almost always qualify for a better rate and term with Key Auto Group than anywhere else in New Hampshire.

Here's why: Key Auto Group maintains cohesive partnerships with over 30 separate lending institutions of all sizes. These partnerships allow us to provide our customers with the lowest possible finance rates and most competitive terms. Our lending network includes a variety of institutions throughout the region.

Here are some of the things that might influence your interest rate:

1) Your own personal credit history: Those with great credit history will usually qualify for the best finance terms. Click here to get approved.

2) The year of the vehicle you're financing:
As a general rule, the newer the vehicle, the lower your interest rate. This speaks to the level of risk the bank is taking by offering financing on the vehicle you've chosen. The newer the vehicle, the lower the likelihood you will have to spend money on repairs.

3) The mileage on the vehicle you're financing: As a general rule, the lower the mileage, the lower the rate. This is similar to the year of the vehicle.

4) The type of vehicle you're financing: Although this is very rare, some banks favor certain makes/models over others.

5) Where you're purchasing your vehicle: Some dealer groups, like Key Auto Group, have the ability to help you qualify for lower rates than you would at other places.

6) The amount of cash you're applying toward the purchase:
Contributing a cash down payment to an automobile purchase often positively influences your interest rate because it decreases the bank's risk position in the transaction.

Here is a list of some of the lenders we can connect you with: Capital One, TD Bank, Northeast Credit Union, Bank of America, Chase, Ally Financial, GM Financial Americredit, Santander Consumer USA, St Mary's Bank, Service Credit Union, Triangle Credit Union, Holy Rosay Credit Union, Digital Credit Union (DCU).
