New and used 2026 GMC Sierra 1500 trucks for sale near George Mason, VA

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.

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!

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.

I felt really welcomed from the moment I walked in Alex was very knowledgeable of the particular truck I was looking for and went above and beyond to make sure that I got just that. Overall I am completely satisfied.

All staff made us feel very relaxed from the beginning. Courteous, professional and respectful regarding any and all questions. PZ was the salesman and had a great sense of humor too. All employees we came into contact with introduced themselves and offered a handshake. Process was quicker than most and gave us the sense of being appreciated customers. The car is my grandson's and I am relieved that he has done business with such a pleasant dealership since he does not live close by. I am confident they will continue being willing to help with any issues he may encounter in the future.

I came in to get a recall item fixed and met Carlos. He was great to work with. He got the car in at the assigned time and I was out of there before the quoted timeframe. Great customer service. Thanks Carlos!!

John has outstanding customer service and patience to detail of being very helpful. John is a asset to the company

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!

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.

Sales persons were very informative and provided quality service. Sales manager took time to confirm eligibility for all possible rebate offers. Financing took time to answer all questions and reached out for confirmation on questions from customer.

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.
