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!

I have always had an excellent experience with service. I had to get my usual service for an oil change and my tires rotated. I was very happy this time because I was having some echoing on my phone calls and they were able to find the problem immediately, I just needed to update something.

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.

The planning ahead and the attention to detail in the early stages of this purchase made the final paperwork and completing the purchase easy and quick. I drove from Greensboro NC, 4.5 hours away to purchase the truck. The truck and all the details were ready, I was promptly taken care of and out the door in about an hour. Had to be the easiest and fastest vehicle purchases I have ever done. Completely satisfied, and happy I chose to do business at Joyce Koons GMC. Hats off to all the team that helped make this happen.

Bought a new car.
Bought a new car. The car salesperson was awesome. First, I called to check the availability. It was in stock; 1 hour later, it was sold and he called me to let me know. Thats okay because that car was heavily discounted. I contacted him again for a car with higher trim. Over the course of one week, he worked with his manager to get me the best deal. I bought the car the following weekend. The car salesperson showed great patience, treated my family with respect and kindness. The dealership paperwork process was straightforward. No headaches. I finished in 1 hour.

All staff made us feel very relaxed from the beginning.
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.
