I was impressed with the service we received with the dealership employees involved with the sales and trading of our vehicle.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

I had an outstanding out-of-state purchase experience
I had an outstanding out-of-state purchase experience with Ourisman Ford of Manassas. Ron Guzman and Elijah Conner made the entire process seamless—professional, attentive, and genuinely committed to getting the deal done right. From start to finish, everything was clear, straightforward, and pressure-free. Their top priority was delivering a great vehicle with exceptional service, and they absolutely delivered.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Go here they treat people right!
Saw a Toyota online and send in an inquiry. That’s when I found out this place is on it. They sent me a video of the vehicle. An email with the CARFAX and window sticker. I found out they have a new General Manager. He definitely understands todays buyers. They made everything so easy. People should know about this place!
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

Very happy with the staff.
Very happy with the staff. They were straightforward, honest, and my car buying experience was hassle free. My sales rep quoted me an upfront price and communicated all additional fees as well. I was given a fair amount for my trade.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Jean is a super star and was the only reasonI ended up purchasing the vehicle. Jean listened, wasn't pushy and should give lessons to others on sales techniques. Excellent communication and great conversation. Michael is great and John was pleasant to deal with also.

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.
