Very Good Experience
I had a very good experience buying a new Outlander from Courtesy last week. This was my first experience dealing with them. Salesman Kyle and the finance guys were easy to deal with; everybody was upfront and honest. I would definitely buy from them again.
2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Ive been in the car business for almost 18 years now and
Ive been in the car business for almost 18 years now and today I had one of the easiest, seamless, and outright outstanding experiences with my sales consultant Nick Cardillo, and General Manager Miles Bedford. I came from out of state to make the deal, and Im a bit particular with how I like my vehicle delivered so I gave Nick a task list before I got there to make it quicker and easier on him at the end of the month and he hit it out of the park. I was in and out in less than 1 hour with my new Hummer EV. He even made a special trip on his day off to make everything was perfect for me. Customer focused service is so rare nowadays and I am so thankful for the Tasca teams commitment to that. Bravo and much success in the future! I appreciate you all.
Good afternoon everyone, yes, I’m a lady and I’m an owner
Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Awesome inventory and even better customer service
Matt is Excellent. Outstanding customer service he is knowledgeable and quick and made the buying process a breaze. He went out of his way to make our experience the best it could be and stayed late to make sure my Wife could take hers home same day. I bought 2 cars in two separate trips on Saturday in the time it would take to buy one at other dealerships. This is my 4th car from AutoMax and have never had an issue with any of the vehicles or the experience. This is the place to go and I will be buying my next car there and asking for Matt.
2022 GMC Sierra SLT 3.0 Duramax
My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Great old fashioned way of doing business.
Great old fashioned way of doing business. Professional, smooth, non-rushed atmosphere. Mr. Paul Macchi is a great, concientious employee. I thank him for his courtesies and cordiality.
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

It cost a lot to get the car repaired.
It cost a lot to get the car repaired.. overall dealership is good but every six months I need to spend $300 on service? it?s very costly to afford a car.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Sales process was very easy and quick. Sales, financing and service/parts department were all knowledgeable and helpful.
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Whenever I need to service my Enclave, I always reach out to John G. at Tasca. He always gets me in quick and makes sure I am satisfied with everything prior to leaving. I appreciate him always checking to see if something is covered by my extended warranty and always lets me know other costs up front. Thanks for your help!
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

If I could give more stars I would I have never been
If I could give more stars I would I have never been comfortable dealing with dealerships and car salespeople in general . I did a lot of searching at different places for my new vehicle .I found what I was looking for at McGovern Westborough .Here I met Ben Fasano . I was pleasantly surprised .He was extremely helpful in not only finding what I wanted with absolutely no pressure. But Even after I purchased the vehicle he has been helpful with the registration and all that goes with putting it on the road. Not only Ben but all the people at this dealership made me comfortable with purchasing a vehicle here even though it’s 30 miles from home. So far so good !!
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Great dealership.
Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

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!
