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.

Quite simply, two guiding principles determine everything we do: Car Buying Made Simple, and the Lowest Price... Period. 
More about Key Auto Group's Pricing Philosophy

We make the car buying process very simple by displaying the lowest price on the window. We price our vehicles more aggressively than anyone else in the area. For that reason, we're proud to display it on every vehicle's window.

We believe there is more to buying a vehicle than worrying about the price. For that reason, Key Auto has simplified that process for our customers. When we price a vehicle, we take the following into consideration: 1) market conditions, 2) what the area dealers are selling them for, 3) Kelly Blue Book* retail. This way, when you leave a Key Auto Dealership, you're confident you've received the absolute best deal.

When the Key Auto Group was formed, the owner realized that most customers were tired of buying cars the "old-fashioned" way. This involved negotiating back and forth over a price, and being pressured by the salesperson. This could last hours! The customer would end up driving away in their new vehicle with no assurance that they received the best deal possible. That's not how we do business!

We believe customers want to focus on the important aspects of buying a car, such as reliability, safety and integrity of the dealership and its staff. All that can get overlooked when focusing on price alone. Here at Key Auto, you can rest assured that you ARE receiving the best deal possible. We'll prove it!

This is the hassle-free zone. Welcome to the Key Auto Group.

Thanks for all the hard work you did.  Just love my new car!

Mary Ann,Portsmouth, NH

"Thank You"

Sometimes in the retail world, some folks forget the importance of customer service and how much value it can add to a business, especially in times of scarce resources and shrinking disposable incomes.  It's a true professional that can combine sound business practices and a "neighborhood" type of sensitivity to all of your customers.  Thank you for your service and kindness.


"Love this car!"

The sales department at Portsmouth Used Car Superstore is fantastic.  We have purchased an Audi A4, Toyota Tundra, Acura TL, and now a Lexus ES330 from the store, and the salespeople and managers have always treated us with an exceptional level of professionalism.  I will continue to buy all my cars here because the whole experience is so easy, there's no haggling, and their prices are the best.  Plus they work with my bank.  This is the right place to go!

Jen and Brad,Dover, NH

"Great Dodge Caliber"

I am writing to express my pleasant experience with your salesperson Pete Leonardi.  Pete offered a no-pressure sales environment while being incredibly helpful and knowledgeable about the car being sold.  As with any auto purchase, I was hesitant to spend money on a pre-owned vehicle, but Pete put my fears to rest and helped me receive a great deal.  Thank you Pete!

Scott D,Salisbury, MA

"John did a great job!"

He was friendly, informative, and very helpful!  I was looking at one car, told him what I wanted and he pointed my new Volvo XC90 out to me and I was hooked!  He knew exactly what I was talking about, for my needs.  I would definitely buy more cars from him!!

Debra,Brentwood, NH

"Still trying to decide?"

When I came down for my test drive I bought it!!!!  I dealt with Brandon Small, who made the whole process pleasant, informative and easy.  If all the co-workers have personalities like Brandon's...... what a great place it must be to work - and, I can attest to what a great place it is to purchase a car.  I plan to pass my pleasant car purchase experience with Portsmouth Used Car Superstore, and especially Brandon, on to my friends and everyon else who will listen.

Pat A,Kittery, ME

"Thank you! "

Brandon and Jon,
I just wanted to send an e-mail to thank you both for your outstanding customer service when we were trading in my car a few days ago.  There was no pressure and no hassle - you guys were great!  i've been to a lot of car dealerships before, and this was by far one of my best experiences!  Again, Thank you!

Mallory and Dan

"Many Thanks"

I have finally had a chance to sit down and write.  Apparently a great new car makes time fly!


Thank you so much for helping make our car-buying experience with you so easy and literally pain-free.  Buying a new vehicle is not something my husband and I enjoy.  The fact that neither of us likes haggling has always left me feeling like we would end up missing out on a deal because we didn't want to play the game.  Our experience with you left me feeling quite the opposite.  Your prices were absolutely reasonable - not so high that it was obvious that games needed to be played, and not so low that you had to wonder what was really wrong with the vehicle!  Your offer for our trade-in was, again, very reasonable and left me feeling completely free from those silly games.  I appreciated that you were willing to find a way to get us into the car that would work for us, based on what we were looking for, and not based on what would benefit the company.  I felt no pressure from you, only that you wanted us to be honest and let you know what WE needed so you could help us find what would work.  The minor tweaks and fixes that were needed to make the car like new were equally pain-free.  Ken in Service could not have been nicer.  I have to say that our whole family loves our car, and most people are surprised to learn that it isn't brand new!  It looks great, and runs great, and I'm thrilled to finally own a Toyota.  In addition, Jon Miele was clear, helpful, and fast so that we didn't have to spend too much time signing forms while our kids were itching to drive off in our new car.


I can assure you that I have already told people about our experience and will continue to do so.  If I find out about anyone looking for a car, I will make sure they go to see you first.


If I could afford to buy a car more often, you'd be seeing more of us!  In the meantime, I'll just have to do my best to send people your way instead.

Happy Customer
