Jimmy at Carmart.
Jimmy at Carmart. was absolutely terrific. Out of the dozens of times I have bought a car from anyone this was the most smoothest ever one that I felt no unease about. Jimmy took care of a problem after the sale with no hassles even picked up and delivered my wife while his crew worked on the car. By far the best dealership I have ever worked with. If you’re looking for an honest dealership that you don’t feel will cheat you this is the one.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Great service and friendly people.
Great service and friendly people. Donna an is the best. The SUV is running great.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Excellent as expressed.
Excellent as expressed. Mr. Donovan was my advisor and he conducted himself in a manner that was extremely impressive. He was extremely knowledgeable and professional. He is a front man for this company and he represented himself very well. I appreciate this type service and will continue to return and will share my experience with colleagues.

Highly recommend the team of Jason "JC" Burthey (sales),
Highly recommend the team of Jason "JC" Burthey (sales), Tony Blazier (sales manager), and Scott Cook (Finance) for your next car purchase. Professionals all around who made the process easy for multiple car purchases. I do a decent number of commercial/business vehicle purchases (8-10 vehicles/year), and these guys were great at cutting through the noise to get to our target and not waste my time...and with no surprises. Their consistently great inventory helps too -- kudos to the folks who manage their allotments from GMC. We've now bought four vehicles from Koons Woodbridge in the last six months, and I'd be happy to go back to them again for a personal or commercial fleet purchase. Thanks, guys!

While visiting our daughter from out of town my husband
While visiting our daughter from out of town my husband was looking for a truck. With two days remaining before we were to leave to come back to NE my husband found a truck at Car Mart that checked all the boxes. He spoke with Jimmy and confirmed some information and we went for a test drive. There was a little rotor noise and the two rear tires were quite worn. When we let Jimmy know about those concerns he had it pulled into their shop, they fixed the rotor and put two new tires on the vehicle on the spot. We bought it and our real "test drive" was our 1200 mile return trip to Nebraska. Our experience was wonderful and I would recommend CarMart, and Jimmy in particular to anyone shopping in the Manassas area.
