Midway Automotive review
Great service very friendly and professional. No stress with test driving or even "talking numbers" it was a great experience and will go back there again.
2022 INFINITI Q50 review
IF you want to take a powerful car on a smooth ride, buy this car. It is so luxurious and has almost every bell and whistle I can think of. The value was great. The dealership not so great, but, I love my new car. It is so spacious and almost no detail went unthought of. Definitely a 5 of 4.9. The only thing I don't care for is the shifter doesn't make sense. Why is the Park setting a button while the shifter is separate. It should be the regular shifter. Doesn't make sense to me at all. That's the only complaint I have. But in time, I'm getting used to it.

Very professional, fast and easy process. All staff very attentive and not pushy when showing cars.
2017 INFINITI Q50 review
The color grabbed my attention and the response kept my attention. It is the most fun vehicle I’ve owned so far. From the standard mode to the sport mode it’s fantastic but put it in sport + and it’s a thrill!!

Have a great experience buying a Hyundai Ionic 5. Kevin was so help full showing me all the features the car has and how to get it to charge. I am grateful for all the time he spent with me.
2023 INFINITI Q50 review
Great and fast car for the money. Reliable as long as you keep up with maintenance. Good alternative then a BMW and cheaper to maintain. Haven’t had any major issues.

DriveMax review
HE WAS VERY HELPFULL AND FAST !!! I RECCOMEND !!! EASY AND QUICK AND WORTH IT !!! ty
2019 INFINITI Q50 review
This car rocks. The only maintenance I've done on this car is for oil changes, new tires and windshield wipers. Has never broken, has never needed any repairs - none. Superb handling, excellent power, intuitive controls and excellent visibility. Audio system is excellent too. The only drawback I've experienced is the trunk - it's little. However, the rear seats fold down independently and larger items can go in the trunk if you don't mind folding down one or both of the rear seats. I traded my 2017 Jaguar XE twin turbo sedan for this car and I have no regrets. Some posts have indicated that Infiniti isn't what it used to be - and they're right, This brand is exceedingly better than it used to be. Just my two cents.

Colonial Honda of Dartmouth review
The process of finding and deciding to buy the vehicle was good. The salesman was great. Working for us through the whole process. Our issue was with the finance woman. Rushed through the whole process with little explanation. After leaving the dealership and going through the paper work line by line we discovered the following. There were math errors (figures off by $2000, she charged us for maintenance plans we said we didn’t want, had the amount we were financing wrong by +$4000!! We went back immediately to get all the mistakes rectified and only got double talk for excuses. I have never had this happen before while purchasing any other car. Buyer beware of the finance process!
2020 INFINITI Q50 review

2018 INFINITI Q50 review
Drives and handles very well on the road. The only surprise was during purchase. I expected it to have a Bose sound system like my G35 had, and the automatic front seat and steering column. On my G35 these two systems moved in unison and had memory for the position of the seat and steering column that could be set for two different drivers. The only other thing is the absence of a spare tire. Those run flat tires ride very hard and are not cost effective for owners.

Anchor Auto Group - Subaru Nissan review
Described my issue, any other maintenance I wanted done, was given the price up front, sat and waited for the job to be done, paid for it, went on my way. Free coffee, other drinks, and snacks. A nice Home DIY channel playing on the screen in the waiting area. 10/10 how it should be.

Milford Nissan review
I recently purchased my second Nissan Rogue from Milford Nissan. The entire buying experience was easy and hassle free. Jim our salesman was friendly, personable and knowledgeable. He put me at ease from our first meeting and there was no pressure to purchase. He offered sound advice regarding both the vehicle and a possible purchase. The entire staff was very easy to work with. I got an excellent deal on a 2025 Nissan Rogue Rock Creek. Mr. Wood the financial person was also easy to work with. His approach was professional. He offered sound advice with no pressure to buy. I would highly recommend Milford Nissan to anyone looking for a relaxed buying experience and knowledgeable staff.
2019 INFINITI Q50 review
This car has been great so far, lots of safety, decent amount of tech some of it a little dated, the car is pretty quick with the twin turbos, it drives and handles great. Interior is comfy with a fair amount of legroom and a decent amount of trunk space.

The Q50 does well in many situations. Some models I test drove had exceptionally loud road noise for any car within a luxury marque. A bit perplexing.

Foxboro Auto Gallery review
Very friendly and very knowledgeable. This was the first time in my life that I bought a car within 2hrs. I usually take 2 days to make up my mind about a car. When I showed up at Foxboro Auto Gallery I talked to the manager about the car I've been keeping an eye on. He told me everything about the car. He gave me exactly what I wanted for my car. And after the test drive I went to my bank and before I knew it I was driving home with a CR-V. WOW I mean WOW!! Great experience
2014 INFINITI Q50 review
Yes with a caveat. Overall I generally enjoy my car but issues with going through tires and maintenance issues . Because of that would probably not buy again
