I recently purchased a 2016 GMC Sierra 2500HD from Car
I recently purchased a 2016 GMC Sierra 2500HD from Car Five in Nashua, and the experience was seamless and stress-free. The buying process was straightforward with no unnecessary delays, making it one of the easiest car purchases I’ve ever had. There were two clear fees disclosed upfront: a $795 administrative fee and a $699 paint protection fee, so everything was transparent. My salesperson, Joe, was incredibly professional. He listened to my needs, answered all my questions about the truck’s history and features with complete honesty, and helped me feel confident in my choice. There was no pushy upselling, just genuine expertise that made the experience enjoyable. In the finance office, Stephen was equally impressive. He handled the paperwork efficiently and explained everything clearly without any pressure. It felt like he was there to help, not to sell. If you’re looking for a reliable used truck, Car Five in Nashua is the place to go. Great team, transparent process, and an excellent vehicle. Highly recommend!
Perfect for the family of 6 like me.😍😍😍
I have this car for almost 6 years I have no major problem at all. We always use this for long drive and short heavy cargo. Excellent SUV.

Friendly reception, mechanical inspection mediocre
Two weeks ago we found a Jeep Rubicon on their lot that we liked, low-mileage with lots of pricey off-roading upgrades that made the price seem reasonable. My husband was thrilled. We decided to make the two hour drive from Southern Vermont, and were greeted warmly on arrival. We had easy rapport with Ted, and excellent conversation during the long financial process with Zach (okay, if I’m honest it was only long because we couldn’t stop talking). Three days later we returned to pick up the Jeep, which needed an O2 sensor. A couple days later my husband noticed the Jeep didn’t have a muffler - someone had taken it out and their mechanic apparently missed it - the sound hadn’t changed from our first visit and test drive. Fortunately, a quick phone call sorted it all out. All in all we’re very satisfied with our experience despite being a little surprised such an obvious piece, needed for inspections throughout New England, would be missing from the vehicle. However, their assurance that they must sell an inspection-ready vehicle, and quick action to right the issue saved their review, and our overall impression. Thanks, guys! We can’t wait to get out on the class 4s!

Buying Made Easy
Buying a car from Mo was great. I do not like buying cars. I do not like the standard buying script. Thankfully, Mo talked me through the process. Showed me a coupe of vehicles and never pressured me to buy. With his assistance, I was able to make the buying decision that was best for me. In my experience, the prices were more than fair. The team was awesome and they continue to work with you after the sale closes. If you have researched your desired vehicle. Know the prices and what is available. Go see Mo. He probably has the car for you at a great price.
Love this car
This car met all my needs and more. Love the interior and the way its moves. So comfortable and reliable! Very pleased with this car!

Nice dealership, pleasant experience
My wife needs to retire her car. We are looking at three brands and this was our first stop. We spoke to Brockton and he made it a great experience. If she decides on the Mercedes we will be back.

I’ve had many Mercedes-Benz models over the years, including AMG’s and the GLS 450 a wheel drive with 23 inch wheels makes this car track like a race car. Out of all the Mercedes-Benz models this is the best one you’ve ever had. The second row seats reclining just like the front row seats privacy shades and the third row comes in handy when needed plenty of cargo space for all those trips to the airport to pick up family and friends. It gets great gas mileage then other SUVs and it doesn’t look like a box like it’s competition. I had the dealer put the Mercedes-Benz standup medallion on the hood even though it has a huge Mercedes-Benz insignia on the front. I just like to see the stand up Star medallion from the driver seat guide me down the road..

Ms. Mabie was great! She was very responsive to my questions and was quick to get back to me with my requests. Too bad it didn’t work out this time around, but will be keeping her in mind with future car purchases!

Amazing dealership inside and out.
Mercedes-Benz was extremely helpful when it came to helping me with the purchase of my new C300. The facility was immaculate and team very accommodating.

Gold star treatment
Went to 3 other dealers before being reccomend to matt Harris and knew instantly it was our last stop. We has been treated like xxxx at the other dealers. 1 lied to us and another told us he would not replace bald tires on a 2 year old luxury vehicle. The second we met Matt we knew we were In great hands. My fiance got the Mercedes she wanted at a fair price and the vehicle recieved everything it needed in the shop before we looked at it. The finance guy treated us like human being and never once felt like I was being had. Oh I forgot to mention that I sold cars for the last 17 years so I recognized great people right away. We will always be loyal to Matt and appreciate everything he did for us
Great SUV
My 2 honest cents. Just bought the 2024 GLS 450 and it has a huge presence on road and it looks stunning! I went with the AMG exterior package and it looks way better than the base model. Ride quality is good, very smooth ride on freeways but you do feel small bumps on occasional city roads. The engine is good but I wish it had a bit more power, feels little laggy at low speeds but when you floor it it moves fast and steering is very responsive. On the other hand, cabin very silent tho and you barely get to hear road noise (without acoustic package). The Mileage is incredible on this, wasn't expecting to write about it but the GLS gives better mileage than my GLC. Interiors are amazing and is something no other manufacturer in this segment can match (especially at night with ambient lights), seats are super comfy and the infotainment screens are also crisp. Overall, love this SUV and i'm gonna keep it for a while.

As good as their word!
I always have an interesting car. I recently bought an AMG SLS Gullwing Coupe from MBOB. The sales associate, Mike, was exceptional. I did not have the car inspected, since MA has an auto warranty requirement. When I received the car, it did have a small oil leak. I have to say, I was concerned, since anything on an AMG car is expensive. However, after corresponding with Stephen (MBOB Service Director) and Tim (General Manager) they were good on their word and they coordinated with MB of Tucson for a valve cover gasket replacement. The car is fabulous, its condition is now perfect, MBOB's response was great, and I would not hesitate to buy a six figure car from them again!

Greg Longo in service went above and beyond for me yesterday. Highly recommend Smith's friendly and knowledgeable staff. I will use Smith Motors for any warrantee work in the future.

I usually get SUVs or Trucks from American Brands. I wanted to get my self a really nice seadan. My buddy recommended me to go to Mercedes-Benz of Burlington before I go to any other luxury dealership. His recommendation was spot-on. Dealership is beautiful with a waterfall fountain plus a nice cafe. The staff is extremely accommodating. I met Collin Stankard valet who took me to TJ a sales associate. TJ was patient and helped me find the right car for my needs. Chris Caputo GSM took the time and found the proper numbers to make me happy because I like to haggle. Then I sat down with Steve Baker a finance manager me made the paperwork easy peasy. Elaine PC had an awesome delivery for me. I learned the ins and outs of the car. Tim Martino the GM was out on vacation but made sure that everything was done properly and I was treated like a VIP. My father was in the car industry. I know the games and gimmicks the people like to run. I'm extremely happy that I only had to go to one place and had a great experience. I'm now part of the mbob family.

Excellent experience.
I contacted them for a car listed on the Internet. It had been previously sold but they assisted me graciously and offered to find me a vehicle.
Very happy with my purchase from RBM Alpharetta.
Very happy with my purchase from RBM Alpharetta. The car has a very comfortable interior with all the features available. Handles well in town and on long drives. Good acceleration for such a big vehicle. Love the contemporary exterior.
