Flood is Fantastic
I will never buy a vehicle anywhere else. FLOOD Ford Group goes above and beyond. They are trustworthy, reliable and will get the job done. This is my second purchase from them and once again I am thrilled with my experience. Thank you Joe Cicchetti, Joe Cichetti Jr. And Joe Pezza, you are my dream team!
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!

They were so accommodating, professional and polite. They follow up often and care about you as a customer, not a number: very much recommend! They saved my Toyota from needing to be scrapped before I was ready.
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.

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

?????????? 5/5 ? Outstanding Experience from Start to
?????????? 5/5 ? Outstanding Experience from Start to Finish! I recently purchased a Hummer from GMC and had the absolute best experience I've ever had at a car dealership. Jacob M. was incredible to work with?professional, friendly, and genuinely dedicated to making the process smooth and enjoyable. From the moment I arrived, Jacob made me feel welcome and informed. He answered all of my questions, took the time to explain everything about the vehicle, and never once made me feel pressured. His knowledge and honesty were a breath of fresh air. I also want to give a huge shout-out to the entire team?from sales to financing. Everyone I worked with was courteous, efficient, and made me feel like a valued customer. They helped me pick out the perfect vehicle and made the financing process simple and transparent. If you?re looking for a top-notch dealership experience, I highly recommend stopping by and asking for Jacob M. and his team. They made this Hummer purchase one to remember!

Aaron Maldonado
Aaron maldonado, I would like to thank Aaron for all his help. Aaron was very kind and professional he went out of his way bent over backwards to help me by the vehicle I wanted. He brought two Jeeps up to the door so that I could look at them side by side he was very helpful he answered all my questions. There were many options that I did not know about that Aaron told me he was very informative very kind and he was also funny. Even though he was a very serious salesperson he had a good sense of humor I really enjoyed talking to him. Even though in the end I walked out of colonial South Dodge without a vehicle not due to Aaron Sales education but because the manager and myself just could not come to terms with a financial agreement. But again I want to thank everyone at Colonial South Chrysler Jeep dealership we were treated kindly and professionally by all staff members and I would have no problem recommending your place of business for anyone looking for a vehicle, thank you so much and everyone have a great day.
