Bought a 2017 car there in 2019 and I have had more issues with it than I did with my older car that was more than 15yrs old. I've had battery issues several times, I've had to put tires on ( even though i was told they were new tires) and now the car won't start. I called AAA and they said it's not the battery so now I have to be thinking of putting more money into it. I'm very disappointed. I shouldn't have to be putting so much money into it already.

I will start by saying my buying process at Portsmouth Used Car Superstore on Woodbury Ave was as smooth as can be. Andre Owens, my sales guy was great. I was in and out in 1.5hrs with the Jeep I’ve wanted forever.
However, it all went downhill after that. There was an advertisement in the window of the Jeep stating there was a 6,000-mile… warranty, which I was told was a misprint by the sales manager Pollini Reed. Typically, when businesses make an error, they honor what they advertise, but he refused.
There was also a hole in my front bumper that he agreed to fix upon purchase. I

Derek was my salesman and he handled everything quickly and efficiently. Even set me up to have extras installed in my vehicle after the fact. I would definitely use them again in the future.

Bought two cars in 6 weeks here. Straight up pricing, no pushy sales tactics, great salesperson Travis. Happy with both cars months later. Would buy again, great rotating selection of vehicles. As for the service department, use your own mechanic, this one is less than stellar.

Absolutely amazing service, was on and out with a new car Within a few hours. Derrick was super helpful and was really a great salesman. No hidden fees, no pressuring, no having to sign anything to see prices or such, one of the best places top go for a car. The lowest price right up front, and I got mine for a fair and low price!

I have been here a couple times. Once to test drive a car and once to sell one. When test driving a couple years ago, there was a very no pressure approach. I took the car for a ride and once I returned I was asked if I had any other questions about the car. I was then handed a business card and just told to call if I was interested. Was very pleased with the whole interaction. Recently I returned to see if they would be interested in buying a used car from me without purchasing one from them. They gave me a very fair price, and the transaction was seamless. I'm happy to have done business with

I had a great experience yesterday with Travis. He worked hard to ensure I was getting into a car that met my particular needs. He went above and beyond and I would highly recommend him to anyone.

I just purchases a used vehicle from Portsmouth used cars and my experience was amazing. I felt no pressure to make a decision too fast and Craig took his time to listen to my requirements in vehicle options. This was by far the best experience purchasing a car I have ever had and would highly recommend going to see the staff and large inventory they have there. I will definitely be returning here to purchase vehicles in the future. Thanks for making this a pleasurable experience
