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.

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Great experience!!
I had a wonderful experience with carmax in Westborough. Very friendly staff, very clean. They don't harass you. Upon entering the building, I was greeted and directed to the vehicles I was interested. I ventured the lot on my own and able to check out the vehicle. All the details were located on the window or they have touch screens with the info of the cars on the lots. Chris C was my sales person, he was very quick to respond to questions I had after I left the lot and also gave me detailed information about the cars I was interested in purchasing without haggling me to buy the more expensive car. When I had a question for him he would always answer it and send the brochure or the car detail info so I had it. The day I made my decision I was driving off the lot in a preowned vehicke within a few hours. I was extremely happy with my experience and would recommend Carmax in Westborough for anyone searching for a preowned vehicle. And i had been to other dealerships for test rides.
MY TERRAIN
I leased this car before deciding to buy. Its a reliable vehicle and I have never had any break downs since I have had it.. just regular matenance

Very Accomidating
I am a super busy person. I called to schedule an oil change and they met every need that I had. Including letting me go before they open to have my oil changed. It was done so fast and effectively I was not late for work and I could not be happier. If you want a place that will service your car with a smile...and get it done right. This is where to go.
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

If it wasn’t for the Service Manager Dominic and Customer
If it wasn’t for the Service Manager Dominic and Customer service rep Matthew who works for Dominic, the vehicle would have been sold months ago! They both went out of the box to get all issues fixed . I can’t say enough about these two and have repeatedly tried contacting the District Manager for Tasca GMC in trying to let him know that they’ve secured our loyalty. We’ve purchased more than 7 vehicles from Tasca and didn’t want to take our business elsewhere. TY Tasca for having such valuable employees. Nicole Saunders Owner of 2024 GMC Sierra Denali .

After searching & visiting other smaller car sales spots,
After searching & visiting other smaller car sales spots, I came across Central GMC Norwood. I had a limited budget & a definite vehicle in mind & found it there at Central! From the initial viewing & test drive to the closing & picking up the truck…my total experience could not have gone any better! Salesman JT Price is a rare, truly genuine, no xx kind of guy/salesman & I felt totally confident in my dealing with him! Couldn’t have hoped for a better truck buying experience! I highly recommend JT & Central GMC Norwood for your next vehicle purchase…you will not be disappointed!! W. Watson
