I bout this truck new in 2008 and traded it in in 2020. This truck gave me 12 years of reliable transportation. I used this truck for everything from commuting to work to camping with the Boy Scouts.

Great and trustworthy team! This is my second vehicle purchased from them, and I couldn’t be happier. I’ve checked other options, but their prices are much better for the same mileage. Highly recommend these guys!”

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

Sales persons were very informative and provided quality service. Sales manager took time to confirm eligibility for all possible rebate offers. Financing took time to answer all questions and reached out for confirmation on questions from customer.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

Great selection of cars. Everyone there are helpful and honest, and have made my buying experience super easy. I would not go anywhere else!

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Bought it from my sister. Best vehicle I've owned. Very comfortable and has plenty of power. Love it. It's like anything else you own, regular care & maintenance goes a long way.

I have a 2010 Escape snd have gotten all my service here. Yesterday Daniel was very helpful.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Josh was great and made the whole buying process run smoothly. He was very knowledgeable and even set me up with the my Chevy app which is very convenient.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I had a wonderful experience with Caleb Polen, both trading in my vehicle and purchasing the new one. I would highly recommend Leesburg Buick GMC and Caleb.

Pascuale and Sang were nothing short of AMAZING and professional! Pascuale met me at the door upon my first visit at the dealership. His kind and honest spirit allowed me to feel comfortable enough to know, this is the dealership I wanted to use. Pascuale and Sang properly prepared me prior to my arrival to retrieve my custom 2025 GLE350 to ensure zero hiccups. I did not feel pressured at all - just relaxed. My vehicle turned out EXACTLY as ordered! Sang walked me through the basics of how to operate my vehicle and I was also pleasantly surprised with a follow up call the next day from Sang.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Recently got my Chevy Suburban here it was the best deal within 300 miles, happy with the condition and they got me financing beforehand so it only took 20 minutes at the dealership. Highly Reccomend

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

Today I worked with Carlos at Jim McKay looking at a used 2021 Tesla Model S. Carlos was exceptionally professional, courteous, and welcoming for both me and my family. He listened to the type of vehicle I was interested in, and at my request provided phenomenal follow up with me after our gathering with pictures and even a video with upcoming matches. I would definitely recommend reaching out to Carlos -- he is an honest salesman.

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

Levon was my salesperson. He was phenomenal!!!! He made the buying process easy. I truly enjoyed working with him. You will truly enjoy your buying experience!!!!

It's exactly what I was looking for; used but not too used, low miles, good looking but not too many bells and whistles, and didn't need any work.

Client Advisor Arben Vila was a pleasure to work with. Even though we did not purchase the vehicle, he treated us with the utmost respect.

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Salesperson was very helpful on the phone and followed with a text message, I will continue to check Their email.

Everything I want in a vehicle. I love the interior and the slick look of the overall vehicle itself. Oh can’t forget about all the different options Available on this truck. It has so much to offer!

I was unable to purchase the vehicle I was interested in, however CJ seemed to be legit and very helpful to me.

I love driving my 2015 GMC Yukon XL SLT because it's really spacious and it's really great to drive in the winter. It's good on gas and perfect for family 💯💯

Highly recommend working with Ruby to buy your next car. She provided great customer service throughout the entire process. I haven?t bought a car in a long time and she walked me through the process. She stayed after the dealership closed to finish the process with me.

I really like my GMC Canyon 2015 it's a very nice truck .it's been very good ,it does have a couple problems that I've taken care of but all in all I really enjoy driving on the highway in my truck.

Had such an amazing experience! Was a bit nervous to purchase a new vehicle especially in this market but the staff & service were outstanding & comforting. They educated me on every step & were so helpful with any questions/concerns I had. I've been car shopping for some time now but I'm beyond thankful I was able to find DNT. Would recommend to anyone in the market looking for a trustworthy dealership in the DMV. Finally got the Lexus I've been wanting & with the beautiful inventory they have, I will definitely be back when it's time to upgrade!

Car was perfect fit for us in this stage of our life. Looking for a big people mover that was cheap and this worked perfect. I hope we get a few years out of it so I don’t have to worry about young ones ruining a new car.

The service was great and fast. There was not extra add-ons that some dealership try to get you to buy.

Bought my 09 a year ago with only 56,000 miles. Haven’t had a single problem yet, besides the sensors in the tires going out. Driven it almost 20,000 miles since then. Regular upkeep is pretty easy and it’s not hard to work on.

Dealership was easy to find. Employees were very nice and great to deal with. Salesman seemed to have a lot of experience in the car selling/buying business. Some dealerships will try and rip you off, I had no such experience here at South Street Auto Sales. Owner of the dealership stepped in on my purchase to make sure all was going well. I bought a brand new 2013 Mitsubishi Evo with under 200 miles on it. Walked out saving a lot of money. I recommend this dealership to anyone. Nice antique cars to look at when waiting around. I did have to wait a decent amount of time because the finance manager was busy with other customers. No problem for me with the deal I walked away with.

I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍

Great communication on an unusual problem with steering wheel heater that was too hot. Dealership coordinated with GM tech support to resolve snd replaced steering wheel

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain
