Low pressure and straight forward
The sales manager and staff were cordial. I dislike car buying because it?s usually high pressure and high stress. At long, we discussed the car, agreed on price and proceeded through the purchase process. There was no haggling or pressure put o on by the dealership.
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!

Mike was very helpful and professional. He helped me find a car that worked for me. It was a pleasure dealing with him.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

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.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Service
Went in for tires and inspection sticker.The technician noticed the front and rear brakes needed to be replaced or I would not pass the inspection . They had the parts in stock and told them to repair the brakes so I would not have to comeback another day so they did.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

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
