We received outstanding customer service from Luis
We received outstanding customer service from Luis Arredondo when buying a 2023 Chevy Bolt, which I am very content with and enjoy driving. The price was reasonable. Luis was always responsive to our inquiries and focused on our needs. I also really appreciate their Sunday sales hours. Service was great in reprinting the key.

Most people don?
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.

Not really sure I understand but the GMC maintenance that I bought through a different dealership wasn?t as straight forward with other dealerships but she still made it a very easy experience. She explained how the maintenance contract works so moving forward it will be easier. While I did end up paying for service I am still very satisfied with the service that I received and I felt like I was well taken care. I will continue to use this dealership due to the level of of care I received. Great service!

Bryan DeCarlo service advisor in service was exceptional,
Bryan DeCarlo service advisor in service was exceptional, since the moment I left my car for service and with all my concerns with warranty issues. He explained to me every step of the way, he called me every day to give me updates. I am beyond thankful I went I and had him as my advisor he told me what was needed after and felt no pressure. I am 100% happy with the service I received and from the team also working with him. He was really professional and polite and really smart at what his job is. I could keep going in bragging of the service I received. Hopefully people think same as me. Trust me I have had enough ther advisors and not even close to this kind of service.

We discovered an issue when we were buying our GMC and Lucas from the Service department was right on top of the issue. He was extremely professional and a wonderful representation of his company. He verified the issue, ordered the parts and notified us when they arrived. On the day of the appointment, he was there to ensure the repairs went extremely well and answered all questions. I just wish there were more people like him so every experience in all types of businesses would be so positive.

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!
