Used GMC Sierra 3500 for sale

Had a major problem with my vehicle. Def had been placed in with the diesel fuel, a very bad thing. Immediately, we had the vehicle towed to your shop, where the professional diesel mechanics could evaluate. At first it looked like the repairs were going to cost in excess of $20k. A heck of a lot of money. Luckily, it didn't require much other than to change out the fuel filter, fuel pump, blow out the lines, and dump the fuel that was tatted with the def solution. I have since drove the vehicle to southern Virginia and back without any more problems. It is a good feeling to know that when you buy from King Buick and GMC, that they have professionals available to help when a problem arises. I highly recommend King to anyone in the market for a new or used vehicle.

After so many negative experiences with pushy dealerships, we usually try to avoid them. But dealing with Pete at Fitzgerald was a great experience. He helped us get our new car for a great price without any pressure. Thanks Pete! We would definitely come back.

MIKE RANEY IS A SUPER SERVICE ADVISOR. HE KNOWS ME AND MY CAR INSIDE AND OUT. WISH THEY WASHED YOUR CAR LIKE OTHER DEALERS.

Fitzgerald Buick GMC Rockville 5501 Nicholson Lane Rockville, MD 20852 Service Manager Corey Pardue Salesman Paul Cohen Business Manager Tony Hanagan My husband and I would like to personally thank Corey Pardue and Paul Cohen for their professional assistance in purchasing a used Ford Explorer in July. Each of them was patient and personable in walking us through the process. They kept us updated on each step as the vehicle was being prepared for purchase. They were open and honest with the progress of the vehicle. Corey and Paul also listened to our concerns about the Ford Explorer as we originally examined it. We were very pleased that our concerns were addressed in the process. One thing we suggest, the FitzWay Used Vehicle Inspection is verified to be accurate. The air conditioner was not operational when we first looked at the vehicle before the inspection date. The inspection list indicated that the air conditioner was operational. However, the air conditioner was still not operating when I came to pick it up. Corey and Paul took care of it right away and we picked the vehicle up the next day. The open vehicle recalls were completed. Corey and Paul delivered the vehicle cleaned inside and out. Paul helped us to connect our phones to the bluetooth. Our license plates came in sooner than expected and Paul attached them to our vehicle the next day. Shortly before the 45-day warranty expired, the engine check light came on. Corey and Paul interacted with the service department and it was fixed that day. We appreciate the quick attention Paul and the service department did in attending to the engine check light repair. We highly recommend Cory and Paul. We also want to thank Tony Hanagan, Business Manager for smoothly completing our purchase of the vehicle. He was very familiar with the financial institution we used. The salesmen we worked with, Corey Pardue and Paul Cohen, and business manager, Tony Hanagan, would be rated as 5 star each if they were listed below under "Rate the Employees You worked With."

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

Great customer service, everyone was friendly and helpful, waiting for a new vehicle to get to the dealership, will recommend this place to friends and family.

Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.

I am a very happy customer. The exceptional customer service is to be commended. Everyone is friendly and helpful. They really make you feel like you are in good hands.

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

I love working with my service advisor, Chris. He keeps me informed at all times and I have full confidence in his recommendations and he doesn't sell me something my care doesn't need!

Great Trucks! Owned quite a few and they never let me down and seem to hold their value. I will keep buying them for as long as I can.

Nicky just helped us purchase our 6th Acadia at KingBuick. Always friendly and helpful service.

The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Mr John Boehm was great!! I had to take my SUV to Koons Tyson’s Toyota without appointments , his customer service ,diagnosis & discount was outstanding. Everything seemed very efficient & I was happy.

Great experience from beginning to end… and after. Little issue w A/C and they took care of it. Appreciate the customer service and communication. Flight there from NC, Uber, paperwork and back on the road in ~45 min

This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

Everything was great! Mauricio had great customer service

This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

This was the first time that I've used CarMax... always felt that the "no-haggle" thing was just a grift. It's not. Very fairly priced car in pristine condition. They even transferred it for free. Transaction was relatively quick and painless as well. They were even able to take care of the REAL tags and title there as well. If you do your pricing research, they are most definitely an option. And thankfully there was no sleazy salesman vibe or upwelling. Would gladly use them again. Oh, and they actually FILLED the tank, which USED TO BE commonplace, and I didn't have to ask.

This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

Provided proactive service by checking my battery before I even knew it was low

great styling, easy to use controls, trailer hitch already installed, good tires, no dents, and the paint showed no damage.

I brought in my Yukon XL Denali because I was getting a Hood Open alert. Dave from service worked with me and I needed to get my hood latch replaced

Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

My service and inspection was fast. Customer Service, was spot on. Kindness, respect, attentive. I spoke with a few reps, and all were great and personable and professions. That you Country z Chevrolet!!

Best truck ever, will buy another one if I can afford it. Gmc 3500 hd with long bed . Everything a man need
