New and used 2021 GMC Sierra 2500 for sale

Schedule an oil change for a Saturday morning, the staff got me in and out in know time. Great service as always

Always very professional and friendly. We were able to get in on a short notice appointment, and service was done and we were back on the road in under an hour.

Found a car that didn't expect to get. Was a 2014 Mitsubishi outlander which had only 1 owner and good mileage , nice ride. Staff was very friendly and helpful.

First diesel, excellent fuel mileage, much more comfortable and roomy compared to my previous 2016 GMC 2500 New mirror location does pose issue with seeing people or cars (blind spot) Overall extremely pleased

Everything was great! The buying process was so easy thankfully! It was an excellent job done by the staff at this location and their customer service!

Parts advisor Henry V. was good on phone and better when I got there. Had my part ready to go with no hassle. Service advisors Dave G. and Marty were very knowledgable about my key fob programming concerns and made the appropriate recommendations. Service advisor Mary D. did a good job entering my service order, explaining this particular service process and giving me a realistic wait time for the service. I did get my truck back at the promised time and they even washed it for me! I wasn't expecting that. Great job guys!!

Am I the only one that loathes buying a car? It’s supposed to be exciting but man the way those sales people run towards you can be quite a turn off. Not this place! Buying a car was exciting! Didn’t feel pressured. Didn’t feel uncomfortable. Super easy. Prices were verifiably low. I would recommend this dealership emphatically!!

I just purchased a car there today for the first time. They were extremely helpful with everything. From the moment I walked In and was met by a very nice sales Man from Cape Town Africa. He was very attentive! He listened to me and my wishes specially at meeting my budget, everyone at King made me feel very comfortable and not rushed. I am very impressed!

Koons of Manassas always provides top notch service and experience for us. Jaime on the GMC side is great to work with and provides excellent service.

I just upgraded from my 2016 GMC 2500 to a new 2021 GMC 2500. I really liked my 2016 and had decided it was the best truck I had owned in 40 plus years of owning and driving pickup trucks. I just picked up the 2021 and it is a vast improvement in almost everyway over the 2016. The technology, design and ride of the truck are spot on. The new truck is ultra quiet especially for a diesel. I really liked the slightly smaller overall size of my previous truck but I find myself quickly adjusting to this updated version. I have read reviews by others who alledge that the interior is not up to par against Ford and Ram but I honestly don't feel that way at all. Its hard for me to imagine a better package in a heavy duty pickup. I know from experience that this truck rides better than the other two manufacturers as they still emplay solid front axles as opposted to the GMC independent front suspension.

Great service! Found exactly what I was looking for. The first dealership I have ever been too, that we’re not pushing on you. I will recommend this dealership to my family and friends definitely!

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Just want to start by saying home awesome our experience was buying our new car from Krietz! If you are in need of a new vehicle be sure to check out Krietz! We worked mainly with Seth and he was great through every step of the process! Shopping with two kids can be challenging, but Seth made sure to answer all our questions, and even provided the kids with coloring books! Highly recommend Seth to anyone looking for a new vehicle! The establishment is super COVID cautious and even has private sanitized rooms for each client! Huge Plus!

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Big Trucks Big wheels Big Rims!! Hey guys, can I tell you something? I would have to say hands down Krietz’s is one of the best if not the best car/truck/Jeep dealership in the DMV. Working in Pediatric Hematology Oncology it’s very important for me to have reliable transportation; why else would I drive 63.3 miles one way for service? I get so excited when it’s time for Ms. Q to have her checkup (oil change, fluids topped off, tire rotated) all the good stuff to keep her going. It’s been about 3 years since I brought my car from Krietz’s and I have gotten nothing but great service, from sales ( Hi Lisa ) to my own special service crew ( Hi Mr. Phil, Hello Krystal) You guys Rock. Oh yeah; there was this one time when I was getting my car service I became so overwhelm with joy, that was the day Mr. Charles R. Krietz Jr. (Charlie) walked in as I was sitting there waiting while my car was being serviced. I got so excited as if I was meeting a celebrity, it sure felt like he was. He is one of the nicest guys ever I thought to myself when he came over and shook my hand, super sweet guy. PSs… Wait don’t go, there is one more thing I want to mention. These Boys have some Great Toys! I always feel like I’m a kid in a candy store when I go to the shop. Just looking at the trucks all lifted and shiny, Krietz’s has got it going on. Oh, and the Rims, smh. I can’t wait until I graduate nursing school (I will be gifting myself). I am going straight to Krietz’s to purchase a lifted Jeep Rubicon with all the bells and whistles those black leather seats with that red trim, I can see myself now. However, I would probably need a step bar since I’m only 5’2. Anyway, if you are looking for some Bad xxx Toys with great customer service do yourself a favor, go to Krietz’s.

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.

I had been looking for a very specific car for a long time, and I was really excited to find it on Cars.com. It was a weekend and while they were closed I sent a message to see if it was still available. Bright and early the next morning Abby reached out to let me know it was available and she would be able to answer any questions I had. We texted back and forth all Sunday. Monday morning she contacts me, as promised, with information I was looking for and before I know it, I was setting up an appointment to come buy the car! I explained I was coming from out of town and there were certain things I needed to get in place before I came, they were so willing to accommodate all my requests and ones I didn’t know I had! Abby, Lisa, Lindsay and Wes were so great to work with, so professional, so kind and accommodating and patient! I had my share of horror stories in buying cars and being from out of town I wasn’t expecting this to be any different. But it was. If I’m ever in the market for another car, I’ll check with them first! But hopefully no time soon ;)

Great job as always. Service department is always great. They had us in and out in no time. Our service manage, Bill Appel is terrific.

It was so easy to buy our new truck. We had a welcoming and knowledgeable sales staff.
