at Joyce Koons Buick GMC

Salesman Eric Park made the process smooth and easy for us! He was fair, clear, friendly, and easy to work with. We left feeling great about the experience!

Easy to buy, easy to receive!!!

The entire experience was great. My salesperson Luis was amazing to work with no typical salesman games just extremely helpful and answered all my questions. Luis kept me well informed throughout the whole process as my truck was in transit and after delivery he continued to reach out to make sure everything was still going smoothly 10/10 experience.

Shoutout to Santiago! He made my car buying experience very efficient with great customer service! 10/10

I'd highly recommend sales and service and that isn't something I've ever said about a dealership!

Took my 2015 Chevy 2500 in for brake issues (front brakes not releasing all the way) and for trailer brake warning light. To make a long story short got the estimate for the work and had it done. Got it home and front brakes are still dragging. Took it back and after about a week all is good. A while later trailer brake warning going off again, no trailer being towed. Took it back and after 2 weeks got it back. Knock on wood it's been doing good with that issue. The reason I'm giving 5 stars is Koons stood behind the initial work and there were no additional charges to correct the problems. I'd like to thank John Pennefather the service writer for being persistent and also the techs that I'm sure the electrical issue drove them nuts. That's why they get 5 stars. Thanks again

This and Joyce Honda are THE Best service departments I have ever used. We will buy our new vehicles here just because the service department and concierge are that good!

Excellent service at the buick customer service. Thank you Jeffrey for taking care of us, much appreciated. And also thank you Riya and the entire team for great service.

I really appreciate the service the dealership has provided under my service agreement. They always call to check in and ask how they can assist, and everyone I’ve dealt with has been friendly, professional, and accommodating.The service can take a while, but I also understand that extra time may mean they’re being thorough and taking the time to go over everything properly.

Took it in for engine light and $5600 later, it came back on on the drive home. Turned around and drove it back and then the light went out. They tested it to track down the problem and drove it for about a week. Returned the car and all is good so far after a week at home. There was no additional charges. The loaner was great and at no charge. Very nice, courteous, knowledgeable and thorough. I am still working on getting my garage door opener back after leaving it in the loner car. Thoughtful tip, don’t just look down when removing items from the car.

My service visit didn't start off smoothly at all, and to be honest, the experience was about to make me take my business elsewhere. I had to escalate my concerns to management, but I was really impressed with how it was handled from there. Matt, the service manager, called me directly, listened to what happened, and made sure I was completely taken care of—including letting me keep the loaner car while everything got worked out. ​He ended up reassigning my vehicle over to John Pennefather, which completely turned the whole experience around. John was super attentive, kept me updated, and was just awesome to deal with overall—he’s officially my new favorite service advisor. It’s rare these days to find a dealership where management actually steps up, takes accountability, and saves a customer relationship. Huge thanks to Matt for turning things around and to John for top-notch service!

Friendly, very good service adviser, he got a really nice loaner vehicle. Some issues were not resolved but no fault to the service team, they tried their best. We have an ongoing issue with our vehicle so we ill probably be back soon to try again. Thank you!

Professional and explained everything so we could stand the work..

⭐⭐⭐⭐⭐ Had a great experience here. Tanav was awesome to work with and was just a real, genuine person throughout the whole process. He took great care of me, got my trade-in handled, and made getting into my new lease incredibly easy. Everything was smooth and efficient from the sales floor all the way through finance. Never felt pressured or rushed, and the whole team made the experience easy. Would definitely recommend Tanav and the dealership to anyone looking for a new vehicle. Great people, great service, and an easy process from start to finish!

Excellent parts department. John helped me over the phone last minute and got me set up with a new water pump and gave the best deal! Super appreciative of John!

We purchased a 2025 Buick Envision from Joyce Koons Buick GMC with the excellent help and knowledgeable guidance of Steve Hughes. We got a reasonable amount for our trade in car and were able to use our rewards from our GM credit card. Fernando of the financial office was very patient and clear in explaining the paperwork for the financing and what warranty packages were available. All-in-all, ours was an A+ experience!

Customer service is always great. I trust them with all my truck service and repairs.

I came in for regular service and to have new tires put on my Impala. Bryant got me in on time and kept me informed all through the process. My car was due for a fuel induction service as well. Now that the oil, new tires. And fuel induction have been completed, my car run and drives like it is brand new. Thank you Bryant and Joyce Koons GM/Honda!! See you soon!! Jeffery

I appreciate the reminders about scheduled maintenance and the coupons! Your service team is fantastic. Quick turn-around as promised. The concierge option makes Koons the perfect place to go, and it keeps my family safe. HIGHLY RECOMMEND this dealership. Most people don’t think of a dealership for routine maintenance but Koons Manassas as an excellent place to start. Prices are fair. Service is done on time and pricing is very transparent. Give these pros a try.

We have had very good service and plan to use the service department in the future. The dealership has excellent mechanics and communciates often and well.
