Excellent service.
Honestly I was starting to feel Very overwhelmed for a time during the price/payment discussions, but Chris and his team were very helpful and willing to work with me and I ended up with a 2019 Ford Escape that I feel very comfortable in.
GMC 2500 HD AT4

It went well, but I didn?
It went well, but I didn?t get what I wanted for my trade in. Good place to shop for new vehicles. Reputable dealership. I was very satisfied with my purchase.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

It was definitely worth the stop!
I stopped in with my son, a first time buyer who was looking for something to tackle the snow with. As soon as we stepped out of our vehicle, Dominic approached us with a friendly aura and introduced himself with a smile. Ya know, most of the time when you’re greeted that fast as a auto shopper you’re thinkin’ uh-oh another pushy salesman, but that was far from the case. This dealership was helpful and willing to give us a car buying experience that was unmatched by previous lots around the region. The staff is friendly and treat you as one of their own. I will send all of my friends and family here first the next time they’re lookin’ to buy a car.

What an amazing experience!
What an amazing experience! I had the pleasure to have John Khalil as my sales agent, who happens to not only be a welcoming and zealous sales agent at CarMax of Oceanside, CA, but also a very talented painting artist!! He had great compassion for my autistic son and made sure he was always comfortable during the efficient waiting process by offering him a cute CarMax car toy, a CarMax coloring book and crayons. He went above and beyond when complex situations came about during the bank’s verification process. The determination he had to push my situation through with his persistent diligence as I watched him communicate with high professionalism and positivity as a team with his colleagues/finance management team was remarkable!!!! Thank you, CarMax of Oceanside, CA!! You all are an amazing TEAM!! I’m so happy with my car!!!

I was interested in a Nissan NV 2500.
I was interested in a Nissan NV 2500. Viewing several of these vehicles on cars.com and other sites. I decided to make the trip to Trust Auto in Maryland from West Virginia. About a 4 1/2 hour trip. I had talked to David on the phone to make sure the Nissan was still available and explained when I could be there to look over the vehicle. We made the trip in good time only running into one delay. Upon meeting David he brought the vehicle up to the front of the dealership and told us to inspect it, which is what we did. I had two top mechanic with me. While we knew the vehicle had been in an accident, the repair work was very well done on found a few bolts missing. One in the valance and the other from the inner fender. This could have been from the accident or just from being a service vehicle. A little over 94,000 miles on it. The detail shop did a great job on their work. Very chean for sure. After running the computer test, we took the Nissan NV for a test drive. It did not disappoint. Extremely happy with everything we saw and felt during the test drive. Steering was solid and tracked well. No pull to either side while driving. Throttle response was perfect as well as the braking system. The comfort of the Nissan NV was Avery pleasant surprise. The ride was almost as good as my Lincoln MKZ, almost.😎 Much like a 2006 GMC dually I had in 2007. Very nice. When returning to the dealership myself and the two mechanics talked things over and decided to go to the next step. After a little negotiation we settled on a fair price and made the purchase. David was very kind to us and I feel like we got a great deal. We finished the paperwork and was ready to leave but we were blocked in by another vehicle. I backed back into the parking spot when one of the ladies that worked there said she would move the vehicle so we could be on our way. She came back within a few minutes moved the vehicle and with a big beautiful smile waved goodbye to us as we left. That truly made my day😇. Trust Auto in my opinion is a great dealership and when I need another vehicle, they will be the first ones I will go to. Thank you to everyone who was so kind to us while we were there and may GOD bless everyone of them 🙏✝️🙏 Jon

2010 Mustang GT500
I bought a 2010 Mustang GT500 from Tyler at Classic Motor Cars. I was a bit nervous because I was buying a car without seeing it first. Tyler made me feel much better about it. After buying it, Tyler picked me up at the airport and drove me to the dealer to pick up the car. Everything about the process was terrific. The car was as nice as I was told and he even sent pictures of the 2 flaws on the car before I bought it. It was a great experience and a great dealership.
