Most trustworthy dealer. A+ Warranty. Well Priced.
Integrity. Honesty. A+ Warranty. Trustworthy. Reliable. Well priced. Personal attention. North End is the best car dealership I’ve ever worked with. They’re a honest, local, family owned dealership that takes pride in quality and care. Matt is reliable, attentive, and thorough. They took care of me, going above and beyond when they didn’t have to. Unlike other dealers who discourage buyers from having the vehicle inspected by the manufacturer before completing the sale, Matt didn’t skip a beat. With no hesitation he said “make the appointment and we’ll make arrangements to get it there”. Matt could have sold the car before I put down my deposit but he didn’t (even though there was a customer on site wanting to purchase). I’ll never shop anywhere else. Neither should you.
This truck has a jerk when changing gears sometimes.

One of the Best Buying Experiences!
I recently purchased a pre-owned vehicle at the AutoMax in Framingham. I have bought many cars in my lifetime but I can honestly say, this was one of the best car buying experiences I've had in a long time. This was my first time at AutoMax of Framingham and I was able to find the right vehicle, with the right options and at a fair price (compared to your competitors). However, what really made the experience worthwhile and very appreciable was the salesperson Matheus. "Matt" is really a great salesperson. Much different from others I have met and dealt with. Matt is extremely Knowledgeable and professional - Great Hire and Asset! I will continue to do future business with AutoMax and will refer my family and friends as well. Mark
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

We had a great experience at Imperial Toyota working with Majed and Eric. They were friendly, very helpful, and didn’t pressure us into a purchase. We gave them some specs and walked away with exactly what we were looking for! We’ll definitely be going back for all of our services and future car purchases.

Like most people the thought of car shopping is just an anxiety ridden process. I can not say enough about the attention and focus they put on their customer buying experience. The communication was excellent as well as trying to meet my needs by asking the right questions and finding the right car. I scheduled with Jessica Aubin and the cars were ready and waiting. She knew the cars inside and out and was able to answer all of my questions and if she did not know, she went to ask- she didn't try to xx stuff by me. Stacie the GM was fantastic and Chris in finance was so patient with my, no less than a million questions on warranties etc. I never once felt pressured or treated like a bother. Not every dealership can say this. I had some bad experiences recently during this buying processes with other dealers and I wondered where the days went when the sales person not only wanted to sell you a car, but sell themselves and all the reasons to create a relationship with this dealer. Well I found it and I think you will too! I can't see my family going anywhere else in the future. Thanks again for showing that customer service still exists!

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.

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 purchased a used 2018 Honda pilot from Imperial Toyota
I purchased a used 2018 Honda pilot from Imperial Toyota in February. I can honestly say I hate buying cars. Imperial Toyota surprise me. Took their time, sold me a quality vehicle. Unfortunately, we had some trouble with By used Honda, the dealership took care of it right away. I was impressed with the way I’ve been handled. The service team has been exemplary. My oil changes were done in a timely fashion and on schedule. Tom, Fernanda, Soamy, Emily, and the rest of the crew are always in good spirits and make me feel welcome. I’ll continue to have my car serviced at Imperial and I’m fairly certain I’ll buy my next car from there as well
