I wasn’t expecting much going in, but CarMart completely
I wasn’t expecting much going in, but CarMart completely exceeded my expectations. The whole process was smooth and hassle-free, and the car was exactly as listed—clean, reliable, and fairly priced. What impressed me most was how fast everything moved: the registration was completed the same day, and I picked up the car the very next day.
The Perfect Ride
I love this car I bought it for my wife for her Birthday and she just loves it. The ride is great and all the extras it has it perfect

Great Boston BMW service!
Since the 90’s I have owned 5 used BMWs. Once you drive them you don’t change horses. I have been bringing them for service there since 2009. Great service and no need to wait for parts as in other garages. They are stocked. And they treat the earlier models (older) BMW customers as well as they treat someone who is either buying a brand new one or has a new one. They run the cars through the wash when finished and wipe down the interior and vacuum - and it is a very classy touch. The wifi is strong so you can get work done when you are waiting for a repair. It’s painless.
Mixed Feelings
I love the car and at the same time I can't help to hate it. What I love about the car would be the luxurious interior, comfortable and quiet cabin, smooth ride, ease of access, and a few extra features that were put in as an add-on. What I don't like about this car would be the poor fuel economy for the 30i model, especially when compared to the B-58 engine. Apple carplay connection issues, no option for remote start unless I want to void warranty, and no option for the iDrive Recorder App. Exterior Styling - 8.5/10 Interior Styling - 9/10 Comfort - 9.5/10 Cargo space - 8.5/10 Driving smoothness - 9.5/10 Horsepower - 7/10 Fuel Economy - 3/10 It's been an overall fun car to get around in. It's easy to get in and out of, smooth on bumpy roads, and it is quiet. The fact that only 2022 models and newer offer remote start and iDrive recorder is a big disappointment. But I think my biggest disappointment would be the fuel economy. As I had the B-58 in the past and averaged out 11.5L/100km and in this X3 am averaging 13.5/100km which was worse than my pick up truck. I might not keep this car for long-term just because of how poor the fuel economy is.

Great experience!!
I had a wonderful experience with carmax in Westborough. Very friendly staff, very clean. They don't harass you. Upon entering the building, I was greeted and directed to the vehicles I was interested. I ventured the lot on my own and able to check out the vehicle. All the details were located on the window or they have touch screens with the info of the cars on the lots. Chris C was my sales person, he was very quick to respond to questions I had after I left the lot and also gave me detailed information about the cars I was interested in purchasing without haggling me to buy the more expensive car. When I had a question for him he would always answer it and send the brochure or the car detail info so I had it. The day I made my decision I was driving off the lot in a preowned vehicke within a few hours. I was extremely happy with my experience and would recommend Carmax in Westborough for anyone searching for a preowned vehicle. And i had been to other dealerships for test rides.
Excellent Car
I love that BMW makes a mid size suv that is part electric now. We purchased the x3 edrive. I do mostly local driving during the week so only need to fill up with gas once a month to every six weeks. Excellent car!

Best Purchase for the Value and Cost
The BMW X3 is not a crossover that should be ignored. It is more than I expected coming from someone who has owned a 3 Series BMW for the last 6 years. Now I ask myself, why didn't I opt for the X3 much sooner, especially since it is more spacious with better features than my 3 series. Plus the price was only about $3,000 more for plenty more space and amenities. You owe it to yourself to test drive one soon!

Foley Motorsports - Review
I’ve been looking for a Cadillac Escalade for over four months and with absolutely nothing local to my area of Upstate NY I felt the need to explore internet searches. From the moment I first saw this vehicle on Cars.Com I was impressed with the ad presented by Foley Motorsports. The video content, detailed description, financials and pertinent data was all at my fingertips for review. My first e-mail correspondence with salesman Greg Ostrander was impressive. With attention to details he was able to guide me through most elements about the vehicle with no second guessing or (let me check on that) type of response. He clearly is understanding of clients needs and looks to provide whatever is necessary to make someone comfortable with the purchasing process. Ultimately I purchased the vehicle this week and was able to get it home to my residence today. Just looking at it in the driveway gives me a sense of accomplishment that this search process is over and I’ve scored on a great deal. It’s hard for me to explain how this car buying process was the most pleasurable time ever. I just wish this dealership was in my home town.
My dream car
It is just what I expected. It drives smooth and I love it. I would recommend to anyone. The experience was wonderful and made my day. This is my dream car

Felt welcomed the moment we walked through the door. Knowledgeable staff, great prices, spectacular inventory. We found the car we wanted. Frederick helped us with the car, he is everything you want in a salesman. Frederick listened to what we wanted in a car, worked with our price range, he wasn’t that typical car salesman you always hear about, he was great, truly caring. We will definitely return to Autobahn USA when we need another car.

Had an awesome experience at Lexus of Watertown. From the moment I walked in, everything went smoothly. John B. took the time to walk me through each vehicle until we found the right one, and Gints made the paperwork a breeze. I left confident in my choice and really appreciated how easy they made the whole process. Thanks, John and Gints!

Awesome Sales experience! Loved it!
Not sure why all the poor reviews, but I have had nothing but positive experiences with this dealership. As for someone that has had many, many cars in my lifetime, buying my 3rd BMW was a no brainer and this store seemed to have more stock of certified cars than any other. Ill always gravitate back to a Herb Chambers, since I bought two Lexus from the Sharon store and had a great experience with their sales and service (although I would never by another Lexus, but thats a different story). Herb Chambers dealerships are all about exceptional customer service and great relationships for the long term which is what I like. From start to finish, this dealership had great communication from online, text and in person and Ahmed, my sales person was exceptional, friendly and professional and I could not ask for anything better. Great service, great people and quality cars , I would highly recommend this dealership. The location is not ideal, and it is a smaller dealership with mostly cars in the showroom, but they do an excellent job.

just purchased a 2024 BMW X3 from Tully BMW of Nashua,
just purchased a 2024 BMW X3 from Tully BMW of Nashua, and I can't express enough how exceptional my experience was. My sales representative, Noah, was incredibly knowledgeable and kind throughout the entire process. His thoughtful approach made buying a car a truly enjoyable experience, and I wholeheartedly recommend him to anyone in the market for a vehicle. Additionally, I had the pleasure of working with David, the BMW Genius, who came out to provide detailed insights about my new car. His expertise and kindness were remarkable, and he took the time to ensure I understood all the features of my BMW. I am grateful for his assistance and would highly recommend his services to everyone. Overall, I would give a five-star review to both Noah and David. Thank you for making my car-buying experience outstanding! Sorry, Nick in Finance, I’m giving you a one star. I walked in there knowing what I wanted to buy, no finance, cash in hand, and I said I didn’t wanna hear the spiel about all the extras and the warranty. And yet you still made me wait for what seems like a half an hour for you to print off the paperwork, then hand write it down on a blank sheet of paper, when the printed one was right behind you. Not a fan of this sales technique to buy “ Add on warranties”. My whole buying experience was great until it came to the financial “upsell” of the deal. For reference, I was paying cash for my 2024 BMW.
