Used 2021 Mercedes-Benz GLB 250 for sale near Potomac Mills, VA

This was hands down the best car-buying experience I’ve had in all my years. I’ve purchased vehicles from Mercedes, BMW, Acura, Jeep — you name it — and none of them came close to the level of professionalism, honesty, and hospitality I received at Koons GMC in Vienna, VA. The deal they offered was so incredible that I traveled all the way from New Jersey by Amtrak to Virginia. I’ll admit, I was skeptical at first because many dealerships pull bait-and-switch tactics. But not here. Saleam (Sales), Sait (Sales Manager), and Isabella (Finance) all confirmed the deal ahead of time and honored exactly what was promised. When I arrived just after opening at 9 AM, Sales was still in a meeting, but I was greeted respectfully right at the door. Saleam was paged, and the process began immediately. She welcomed me warmly, gave me a brief tour of the dealership—including the much-needed coffee lounge—and handled all the paperwork, insurance details, and my Costco rebate flawlessly. Sales Manager Sait was exceptional. He thanked me personally for my business — something I’ve never experienced from a sales manager at any dealership in the past. He even told me to call him anytime if I had questions or concerns. That level of care is rare. My experience was elevated even further by Finance Manager Isabella. Her energy was absolutely to the moon. She helped close the best deal I could find anywhere in the NY/NJ/CT tri-state area and the entire DMV region. She offered an unbeatable protection package at a discount, covering dents and mileage, and explained everything clearly and thoroughly. She also respected my time, wrapping up the paperwork quickly since she knew I had a four-hour trip back home. I cannot recommend this dealership enough. If you’re reading this review, do yourself a favor and consider Koons GMC in Vienna. I would happily send any of my friends, family, or colleagues here. They’ve earned a lifelong customer.

I love my GLB but two months and ten days, after the purchase, the engine needed a repair which was covered by the warranty. However, we were planning a lengthy trip and was thankful this did not occur while we were a few thousand miles from home. Me and My Mercedes are still trying to figure our communication out. I prefer Waz or Google Maps to their GPS system. Advance notifications of turns and such are better. Other than these issues I love driving her, Gilby.

Very happy with purchase. Purchased on-line and car was exactly as described. Dealer arranged quick delivery. I would purchase from them again.

My only complaint is that the vehicle comes with run flat tires and no spare. The run flat tires don't allow for the best ride, but when it comes to everything else, the GLB is very good.

Ordered my GLB250 with all the right equipment - Spendy as my car topped out at over $52,000. Beautiful styling. I get compliments all the time - I had my car de-badged so there is an air of "What is it?" A few things I wish were standard equipment was the driver assist (radar based cruse control) and 360 camera system - all extra cost. The upgraded stereo was a must - I wish it had more low end sound. The Air Con seems weak - takes time to cool down on HOT days. My car is black with pano roof. I have a co worker who has a GLB and at less than 10,000 miles blown his cyl heads - OUCH $7,000 repair covered by warranty. Seems to be a common fault. The ride is graet - the milage is OK - I average around 21 in town and 30 on the highway. My previous GLA250 got excellent milage of 34 on the highway and 25 in town. I have the 7 passenger and love it - it is great for the kids 5.5 and under but it is not for adult seating. when not in use it has ample storage room. I have the Black w/ night package, advance lighting, pano roof, AMG styling package, Burmister stereo, Prem Package and the 19 inch 5 spoke AMG rims. Just a beautiful car with lots of curb appeal.

I can't say enough good things about this dealership! Sullivan's is family owned and operated and it shows. This is the forth car we have purchased from them. They are extremely fair and always take good care of us. They stand behind their cars and I am so grateful to have a place to go that I can trust.

The GLB 250 is a solid modern stylish commuter. 7 passenger seating with generous legroom for driver and middle seats, the 3rd row seat is perfect for children 5'5" and shorter. When 3rd row is down the rear cargo space is just as roomy as its GLC sibling. The 2.0L 220HP turbine 4 cylinder powerplant and dual clutch transmission compliments each other so well on the road. Standard safety features on our base model is ample for our conservative leisure driving habits. Entertainment and state of the art MBUX information system is supported by 2 10.25 inch displays with 3 user friendly ways to view the driving, performance and entertainment via steering wheel controls, touch screens and center console controls. We opted for the no panoramic roof so we can enjoy our leisure travels supported by crossbars and a cargo box. Overall we love our chosen new Mercedes Benz.

It was a pleasure to be a customer at Mercedes-Benz of Alexandria. I have worked with and bought from different automobile dealerships over 20 years. I informed my sales manager, Mike Prati, who was AMG certified what I wanted from a car. He was the FIRST auto dealership manager who listened when I told him exactly what I wanted my car. Mr. Prati knew more about Mercedes than I could have read in magazines, Car Werk, Edmunds, YouTube etc. He explained the different variables of each model with and pros and cons. He directed me to the E class 450 sedan for a test drive. I personally could not have found the car without his background and experience. I bought the Mercedes pre-owned and certified. What made the dealership a phenomenal experience was how everyone listened and were respectful. Often, customers are talked to which happened at another dealership I walked out of two weeks prior. The goal: sell you something you don’t want. Not at the Mercedes-Benz of Alexandria. Later, I required work on the car. In lieu of calling the Service department I contacted Mike Prati. Who does that? I did. He immediately sent a tow truck, introduced me to a service assistant and I sat back as arrangements were made for a loaner. Mercedes-Benz of Alexandria was organized, cooperative and I had details regarding my car in less than 24 hours. The general manager, which people never see at dealership, called me. He wanted to be sure all departments were working together and I was satisfied. I actually think this dealership off of Pickett Rd in Alexandria has the finest employees. Great attitude. Thorough. Buying a Mercedes? I recommend Mike Prati to sell you one at MB of Alexandria.

Fantastic vehicle all around ! I enjoy being able to customize the interior. Very comfortable. For a smaller SUV I did not expect to have so much room, there is plenty of leg room for a six foot man to comfortably sit in the back seat.

I dealt with Ali he gave me one of the best quote in the nation! He was so great and professional. Unfortunately, I made the mistake of getting my own financing first and then picking out the car I wanted. I wanted a 2022 Highlander but I couldnt get more money for it from my credit union unless I cancelled the loan I already had and re-applied for a higher loan. I couldnt stomach risking being left with no loan.

I took my 2019 Ford Escape for routine maintenance, plus my AC was not working. DeShaun was my contact person. He kept me updated about the necessary repairs and found discounts where appropriate. He was professional, friendly and customer satisfaction was his main goeal. I am going to ask for him in another 5,000 miles. He was fantastic. C Hobson

I can’t recommend this dealership enough. Trivan and the rest of his team were a pleasure to deal with from start to finish. I was treated with honesty and respect and therefore they earned my business now and in the future. Thank you for a wonderful buying experience.

I had an excellent experience at Easterns Automotive of Sterling. Eddy went above and beyond to make the process fast, pleasant, and thorough, ensuring everything was handled smoothly from start to finish. Tony, the manager, made sure the final steps of receiving the vehicle were seamless and took care of my requests right away. The team as a whole made this a very positive car-buying experience, and I would definitely recommend them.

My experience with Rene the salesman was very pleasant and he was patient/professional. Excellent job 👍
