This is my second interaction with this dealership and I work with the same guy every time. Freddy, he is absolutely amazing. Above and beyond not once but twice. Delivered my new purchase to me an hour away. Always a pleasant atmosphere, the service department guy’s are awesome too!

I only write reviews for truly exceptional businesses.
I only write reviews for truly exceptional businesses. Truly great buying and post-purchase experience. My wife fell in love with this Jeep, and Dan let us take it for a test drive “as long as you want”. We didn’t abuse the offer, but went for a healthy drive. Loved the manual, but you always have to wonder if the prior owner wore out the clutch, but no problem as Dan had already installed a new clutch as well as a couple new tires and a couple other things. We returned it and said we wanted to sleep on it. There was no hard sell at all. I called the next day to see if I could bring it to my regular mechanic. “No problem”, said Dan. I took it to my regular guy half expecting to get a report back about a half dozen things that were either worn out, broken, or just missing. As it turned out, my mechanic came back saying, “we couldn’t find a single thing wrong!” He seemed disappointed, so I know he tried to find anything. Even with that, I was a little nervous about the purchase - you know what I’m talking about, that “Am I just buying someone else’s problem?” feeling. We needed a car, my wife loved the car, it came back with a clean inspection, and the price was very reasonable compared to other options I reviewed online. So we went for it. Dan made sure the car was detailed and handled all the registry stuff. Not two days after we got delivery, the engine light comes on. I’m thinking, “Here we go….this is going to cost me”:( We called, and Dan was genuinely horrified, “Bring it in, I’ll take care of it.” Full stop right there. Awesome! We had already paid for the car, and I was not expecting that response. Dan provided a loaner and took what I would call exceptional care of the car not only fixing the what-ended-up-being-a-minor-issue, but also doing a full check, again, post-purchase, just to make sure it was perfect. I waited a month to write this review just to make sure nothing else happened, and it hasn’t. The car is great; my wife is happy. As I reflect back on the whole buying and post-purchase experience, I am in awe. How many companies these days not only ‘do what they say they will do’ but also add in a few ‘surprises and delights’? If you are a serious buyer, go here and buy from DRIVE and sleep well at night based on your good decision made.

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 couldn’t be happier with my experience at Richards Motorcars, mainly due to the GM I worked with, Joe, who was great. He was prompt and very easy to communicate with over the phone and via texts. He answered a lot of the questions I had before I even made it to the dealership. I made an appointment, checked out the car and was able to do the test drive, fill out all the paperwork, and complete the purchase in a little over an hour. I couldn’t recommend the dealership more.
