All I can say is WOW!
All I can say is WOW! I haven’t always had good luck buying cars and got myself into a jam. Neil Peabody was so amazing! He got me into the perfect SUV, he was fast pleasant and to the point Ian and Tim were also so nice and able to help me out in just ONE DAY! I can’t say enough good things about these guys and their customer service A++
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Professional & Reliable: I am very pleased with my purchase and the sales team. Communication was stellar for this purchase, which I found listed on Cars.com. Dave, went above and beyond to ensure I was squared-away before hitting the open road for a haul back to the Midwest with my 2022 Chevy Colorado ZR2. Yes, I am just another happy customer, and a thankful one to have done business with them. For certain, I definitely recommend North End Motor Sales. Just check out their selection; You won't be disappointed. Thank you!! Respectfully ~Eric M.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Great dealership.
Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

I recently purchased a used vehicle from Imperial.
I recently purchased a used vehicle from Imperial. the salesman Gabriel Borrero was amazing. I told him my finance limit and he did not try to sell me a vehicle I could not afford. Ahmad Al-jallad worked for 2 days to get me financing with my low credit score. They will be my go to dealership from now on.

I had an excellent experience at McGovern GMC
I had an excellent experience at McGovern GMC Westborough. Ben, my salesman, was fantastic—he was helpful, never pushy, and kept great communication throughout the process. He really listened to what I wanted, respected my budget, and even took the time to get to know me while sharing a bit about himself, which made the experience feel personal and comfortable. Omar in finance was just as great—super friendly, honest, and transparent about everything. The dealership itself was clean, well-maintained, and in a very convenient location. Overall, the entire process was stress-free and enjoyable. I’d highly recommend them!

I would like to thank the service department for honoring
I would like to thank the service department for honoring my rim warranty. I brought my truck there while I was getting new tires and wanted my rims to get refinished at the same time because I paid for the warranty when I purchased the vehicle and the service wasn’t available at that time. They told me to bring it back. I brought it back almost a year later and my warranty was up. They completed the rim repair and I didn’t have to pay for the service to be done. ZERO cost to the customer!!!! Nucar puts the customer first!!!! Thank You again for the service and consideration!!!!! I will continue to purchase vehicles there as well as getting them serviced 👍🇺🇸
