My salesman was Brett a great salesman.
My salesman was Brett a great salesman. I told him what I wanted, and he found it for me. He was very easy to work with he stayed in contact with me at all times for young guy.

Johnny knew the car, was able to explain all the features
Johnny knew the car, was able to explain all the features and answered every questions. He was friendly and not pushy making my car buying experience pleasant. When I came to pick it up it was clean, had a red bow on the hood, and sign with my name on it. The paperwork process with Ms. Santana was good.

Great dealership.
Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.
