Car looked better than new after repairs
An amazing experience with the service department and collision center at this dealership after my car was damaged by a fallen tree. The process right from the beginning was flawless. Getting the car to the dealership, getting the rental car, the time it took to get the parts and do the repairs was quicker than expected. The ease and efficiency of the repairs and the quality and timeliness makes Gates GMC. Jamie Laskow and his team get 4 stars from me! I will definitely recommend your dealership in the future.

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 !!

From start to finish, the team at Gates exhibited clear communication and professionalism, making the process seamless and stress-free. What stood out the most was the transparency and honesty in every interaction, with no hidden agendas or surprises. I felt valued and understood, and they made sure all my questions were answered.

Great service, great people
I had a fabulous experience purchasing my Sierra. There is NO pressure which is a breath of fresh air. They are extremely knowledgeable, kind, trustworthy, and you will feel very confident in buying from them. I go there for service too and everyone remembers who you are and they come up to you to say hello. If I could give them more stars I would. This dealer is exquisite.

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.

It?
It?s a pleasure buying experience. The sell consultant and the dealer are all friendly, helpful and considerate. The shopping environment is clean. According to the introduction, the after-service is good (because I just buy a new car).

I called Vendetti Motors when the tire monitor light came
I called Vendetti Motors when the tire monitor light came on and showed no reading for the right front tire. The tire was not flat. The service manager fit me in the next day. After testing it was determined that the sensor for that tire was not working. It could not be reset. After being advised of this I asked the service manager to replace it while I waited. Vendetti?s service department is dependable, efficient and courteous.

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.
There are 20 matching cars close to your year range.
