Hands down the best finance team out there!
Hands down the best finance team out there! All the staff were kind and helpful. They found something that worked with my budget that still met all my wants and needs. I thought I was only able to buy a used car but they made a BRAND NEW BUICK work! 10/10 job well done! Oh and the salesman RJ had a nice little beard lol
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

The customer service, the compassion and understanding
The customer service, the compassion and understanding were truly great. Suzanne and Jason were incredibly kind, very responsive and explanatory and provided us with all around amazing service. We were contacted quickly after our online inquiry and Suzanne was happy to help us answer all the questions we had. We are out of state and the process in which the paperwork and transport of the vehicles were done was flawless. We thank you all for your expertise and kindness. We will be back when the time comes and will most certainly refer all who are in the market to your dealership.
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.

Where to begin?
Where to begin? Obi Davis is, without question, the most professional, courteous, and genuinely kind sales representative I’ve ever had the pleasure of working with. He made the entire experience not only smooth and stress-free, but surprisingly enjoyable. Obi went above and beyond to help me find the car of my dreams, and I cannot express how grateful I am for his dedication and sincerity. I also want to recognize Vilay, who was the best—and fastest—financier I’ve ever worked with. She made the approval and paperwork process seamless and efficient, which is not something you usually expect at a dealership. I’ve never been a fan of car dealerships, but this experience changed my perspective. This dealership is honest, welcoming, and truly treats you like a friend. Because of Obi and Vilay, I can confidently say I’ll never work with anyone else. Thank you both—you made all the difference.

I went in knowing exactly what car I wanted to test drive
I went in knowing exactly what car I wanted to test drive and had an appointment with Jean (John) Venant on December 27th. The car (2024 Mazda CX-5) was waiting for me when we arrived. Our salesman was a great guy & seemed knowledgeable about my particular vehicle. It didn't take me long to decide to buy the car on the spot. Baltimore in the financing department fought very hard to get me the best rate/deal available. They even gave me far more for my trade in that I was anticipating. Everyone throughout the (seemingly painless) process was great to work with. We felt very valued. My only "complaint" is the sticker shock I had when I saw all the "dealer fees" on the bill of sale. Many things (window tint, fabric protector, etc) were all things that you only typically see when buying a brand new car and not when buying a used car. And, with any used car purchase, I made sure to get the extended warranty. That's just smart no matter which dealership you buy from. However, I am concerned a bit to read very mixed reviews of the EasyCare warranty company, as it seems they only approve HALF of the claims submitted. Fingers crossed.

I bought my Raptor from Tommie Vaughn Ford (shelter
I bought my Raptor from Tommie Vaughn Ford (shelter green) and it was honestly a really solid experience. Everything went smoother than I expected and there weren’t any surprises along the way. Jason in finance was great to work with. He explained everything clearly, didn’t rush me, and made sure I understood all the numbers. I never felt pressured, which I really appreciated. He also helped me get a really good deal on some warranties, so I left feeling confident about the whole thing. Overall, the team treated me well and made the process easy. I’d definitely recommend checking them out if you’re looking for a Ford. I’m loving my Raptor.
