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!

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.
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.

I would like to especially recognize my Sales Rep, Jeffrey Jones. He was not sales aggressive, very down to Earth, and made me feel lease nervous. He was honest. Additional he worked with Peter and Sosa, who were also great, to get me into a new car. I left a 5 star rating on Google.

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
