I have been with Honda in Seekonk since 2011 leasing
I have been with Honda in Seekonk since 2011 leasing vehicles in 2016 I purchased a gorgeous 2016 Honda HRV service was excellent until I brought my car in for an oil change and pointed out peeling paint around my windows . The dealership said oh didn’t you get a letter warning you about this I said I didn’t they said the letter was issued in 2019. I said I have been here many times since 2019 my salesman always came over to say hello never never never mentioned anything about this defect nor any technician. It was like I got a secret. Needless to say now they wanted to charge me for the paint job and the salesman was actually trying to sell me a new car. My car is a 2016 and only has 34,000 miles on it. It’s prestige on the inside but on the out side it looks like a piece of junk. All the times I was there they never mentioned anything to me as I said when it was too late they treated me terrible.They had a real good laugh. They are great at KEEPING SECRETS but want your money.
STi - Last of the Subie rumble!
The only car that ONLY comes with a six speed stick. Solid, powerful and fun. Incredible grip. Looks like a Toyota Corolla with a wing. Six pot Brembos have the best grip and modulation I’ve ever experienced!

I worked with Brian Paul to look for my first car. Highly recommend him as a salesperson very nice and honest. Thorough and kind. He gets the job done.
Fun on a bun
Four doors and all wheel drive so I was able to justify this purchase to the wife. Super fun to drive. Gas mileage is not the greatest but if that's what you're into you're probably not looking for an sti.

2018 STi Limited
Owned many subies, Outback, Forrester, WRX but it was my first STi. Love the grip, the sound, and the thumbs up I get from other WRX's. Engine is old and the lag is there but just keep it around 4k RPM and you'll be fine.

The Service Advisor, the Subaru trained Technicians, and the entire Service Department will only perform the necessary service and nothing else that your vehicle does not need. Extremely honest folks!

This is the second time purchasing from this dealership. Price was reasonable and customer service was excellent. The sales rep Sean Ali was accommodating and patient and Roxanne from Finance was transparent with the costs. Again, customer service at this dealership is excellent at all aspects including the service department. Will go to this dealership again should I need to purchase another vehicle.

Excellent online car buying experience.
Excellent online car buying experience. Worked with Sam - He made it easy from start to finish; very kind, professional and not pushy at all: Answered all of my questions, provided additional photos and walk-around video. He did all the paperwork, registration and coordinated the car transport to home door delivery for me. I would buy from this dealer again. Great deal on the car and excellent sales experience.

I had an excellent experience working with Dominic Bosco
I had an excellent experience working with Dominic Bosco at HM Brown. He was communicative, informative, and never pressured me to move faster than I was comfortable with. Before coming to HM Brown, I had spent time at a couple of dealerships test driving cars, and the difference between working with Dominic and the typical dealership sales experience was night and day. Dominic made the process smooth, transparent, and stress-free. Even after purchasing my car, Dominic followed up to make sure everything was going well, which I truly appreciate. I’ve had my car for a few weeks now and couldn’t be happier. I would highly recommend HM Brown and Dominic to anyone looking for their next vehicle!

No problems The 4 July keep me from picking the car as it had to be serviced. That is the one thing I would change is no show a car for sale until it’s ready to go with the customer.

Great experience with service department
I have gone to Plantation Ford twice for service on my 2020 Ford F-250 Diesel. Once for routine service, and once for a engine service code. I have been impressed by the courtesy, professionalism, and accommodating nature of all the members of the service team. I am driving my truck from North Palm Beach County to be serviced at Plantation Ford. The best dealership I have found in South Florida for service so far!!

This dealership is top notch. Customer service and communication are excellent. They have interesting and unique cars at this dealership to check out. Welcoming atmosphere to buy a vehicle. They can find and acquire just about any vehicle even if they don’t have it in stock. I would recommend this dealership to anyone.

5 Stars – Great Experience with No Pressure I had an
5 Stars – Great Experience with No Pressure I had an excellent experience at Stouffair Motors! From the moment even before I walked in, the team contacted me and gave me some general information on the vehicle I was interested in! What really stood out was how there was zero pressure to buy. They took the time to answer all my questions, and they even informed me of a warranty for extra peace of mind, because you never really know what life brings. They let me explore my options at my own pace, and made the entire process stress-free. Everyone I worked with was friendly, knowledgeable, and genuinely seemed to care about helping me find the right vehicle—not just making a sale. It was refreshing to deal with a team that prioritizes honesty and customer satisfaction. If you're looking for a dealership that makes you feel comfortable and confident in your purchase, I highly recommend Stouffair Motors.
