We had a great experience with buying our car. They let us go check it out at a mechanic before we bought it. It was very clean and well taken care of. David was great to work with and so was the owner Mike. We are very happy with our purchase! Thank you! :)

I am a second time customer! Derric is awesome he truly isn’t just selling cars to make money he truly provides the absolutely best for the customers! I enjoyed being here at this dealership and left approximately $100 richer in cash! I highly recommend this location if you want a high quality vehicle! I had already spoken with Joseph & Derric before I made the trip, I wasn’t there long before I was in a vehicle and %100 satisfied. 10 stars is deserved!!! I can’t thank you’ll enough!



My husband needed a work van, which he found online at Auto Plaza. He called and spoke to Jonathan. Right after work we drove about 2 hours to check it out. We were immediately greeted at the door and directed to Jonathan. The van was in excellent condition and exactly what my husband needed. Jonathan gave us fabulous service and made the process extremely easy and timely. I usually hate going to buy a vehicle but we had a wonderful experience. I’d definitely recommend anyone to Auto Plaza and to ask for Jonathan.

Great professionalism! Friendly staff. Fast and easy car buying experience. David is amazing! We told him our time frame and what we wanted, and he made it as easy and comfortable for us as possible.

Everyone at the dealership was friendly, funny, and super helpful. They made the process of buying a car stress-free and painless. Shoutout to Tristan and Derric for going above and beyond to get me a lower interest rate, as well as making my mom and I laugh and feel comfortable during this whole experience. 10/10 would recommend buying from them 😊

Jonathan the Oz wizard of car sales was the best salesman, I was in and out within 2 hours and the customer service was unmatched. Will definitely be back for future car purchases. 5 stars ⭐️

David was a great help. It was my first time buying a vehicle he took the time to explain everything and make sure I received the best deal possible. Great experience!
