OUTSTANDING PELLEGRINO!
Pellegrino is simply the BEST dealership, hands down! I have never met a more truthful group of individuals. Sending over so many from my family, in addition to our 3rd set of leases for 4 cars(12 in all since 2015). I would never attempt another dealership; their professionalism, expertise(not pushy-genuine), pricing, honesty, dedication to their customers and unlimited time to answer all your questions, has truly set the bar above and beyond all others. BRAVO PELLEGRINO!
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Fantastic dealership and 1st class sales rep in Caleb!
Fantastic dealership and 1st class sales rep in Caleb!!! A large selection to choose from. Well manage clean store. Everyone is friendly and welcoming. It?s like a candy store ?
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Evelyn Akins was the best! We drove 4 hours to look at this vehicle and from the minute we arrived, everyone was very friendly and courteous. We were introduced to Evelyn and she was so pleasant and patient! She made the whole buying process so easy and we couldn't be more thrilled with our puchase! I would definitely recommend them and would purchase from them in the future!

I bought my Raptor from Tommie Vaughn Ford (shelter
I bought my Raptor from Tommie Vaughn Ford (shelter green) and it was honestly a really solid experience. Everything went smoother than I expected and there weren’t any surprises along the way. Jason in finance was great to work with. He explained everything clearly, didn’t rush me, and made sure I understood all the numbers. I never felt pressured, which I really appreciated. He also helped me get a really good deal on some warranties, so I left feeling confident about the whole thing. Overall, the team treated me well and made the process easy. I’d definitely recommend checking them out if you’re looking for a Ford. I’m loving my Raptor.

I had a great experience coming in for an oil change.
I had a great experience coming in for an oil change. The drop-off process was quick and convenient, and they even offered me a ride to work, which I appreciated, although my job is close enough that I chose to walk. My appointment was at 9:00 AM, but I dropped my car off at 8:00 AM before heading to work, and by 10:15 AM they had already called to let me know it was finished. The service was fast, efficient, and everyone was very friendly. I have always been treated wonderfully anytime I?ve had my vehicle serviced here. Highly recommend! ?????

Hat ' s up to Davis and Ariel
In Today's seller market, the Davis staff did everything in their power to make our purchase of an Equinox as easy as possible as well as affordable as possible. I like the no pushy sale. They explained and let you decide. It helps to have salesmen who are experts in cars. and they do have those. I would pay them a visit for my next purchase, even if just to ask about a brand they dont carry. You will not regret it.

I?ve had two separate service visits recently at Huffines
I?ve had two separate service visits recently at Huffines Chevrolet Lewisville and the experience was amazing both times! My service advisor, Mike McLarty, was professional, communicative, and genuinely caring throughout the entire process. I was kept up to date every step of the way ? from check-in to follow-up ? and everything was handled promptly and with great attention to detail. Mike made sure I understood what was being done, checked in on progress, and even followed up afterward to ensure I was completely satisfied ? it?s rare to get this level of service these days. If you want excellent service and top-notch communication, ask for Mike! I?ll definitely be back.

Mike Rose was our hero when we were looking for a almost new Tahoe. We were in Hickory and Morganton area, we were looking at a Tahoe at another Large dealer in Hickory, they SOLD it while we were looking! Called Mike Rose at Parks GMC and he took our name and number late February, 3rd He told us what he had on the lot and held it for us overnight. We arrived Feb 4th. to look at the 2025 Tahoe, High Country. We agreed on price and we drove it home. Love Mike Rose's attention to detail, southern charm, very nice, going above and beyond to help us. He was patient teaching us the new buttons and devices on the High Country Tahoe. We will purchase another new vehicle from him next week. People are important! Mike listened and treated us with respect and Southern Hospitality when we were looking for a vehicle.
