New and used 2026 GMC Sierra 1500 trucks for sale near Germantown, MD

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.

I recently purchased a 2023 Ford Transit from Koons Clarksville, and I couldn't be happier with the experience. Randy was my sales rep, and he was incredibly helpful and attentive from start to finish. He answered all my questions, kept the process smooth, and made sure I felt confident in my purchase. I appreciated his professionalism and patience—especially with such a big decision. The team at Koons made everything straightforward, and I’m thrilled with my new van. Highly recommend!

Mr Mario adam’s let me check out all the cars in the showroom and the lot and even let me sit in one. As a kid!!

Very professional and competent. I would recommend them highly. Booking an appointment is quick and easy. Turn around time is fast. Their facilities are clean. They are also friendly and funny

Straightforward experience diagnosing a check engine light as a catalytic converter failure. Promptly replaced under warranty. Took only two days including shipping the new part for a discontinued car!

Our sales man Zack was easy to deal with and wanted to make sure we were happy and got what we wanted. Could nt believe how easy the process was to purchase from them. Everyone from the salesman , manager and finance officer were great.

Excellent customer service. Maintenance/service was completed quickly and professionally. Customer service representative was outstanding and knowledgeable . Tracked the service process and reported the status. I will return for future services.

Customer service is always great at Criswell. They are communicative and knowledgeable. I would highly recommend them to anyone who needs their GM vehicle serviced or repaired!

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.

I have been with this dealership since 2016 when they were Win Kelly. Excellent service, the service managers are great.

Salesman provided a very friendly/easy buying experience. Took lots of time to assist in going through key feature and answering questions.

The service team is the best I have encountered in the industry. They are true professionals and provide outstanding customer service.

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!

Very helpful. Usual good service. Fully recommended. I was kept fully informed about the service and cost. No surprises. I was quickly notified about the progress of the work.
