Marco was excellent.
Marco was excellent. I had made a same-day appointment for my tire pressure light staying on. He quickly discovered that there was a leak in one of the tires. He was very happy to inform me that my tire was under warranty and being replaced for free. He said it would take an hour and a half but it only took 25 minutes! And they even washed my car! I am always so happy with the treatment I receive And the service of my car at Toyota of Plano. I won't go anyplace else!

Had a great experience at AutoNation USA in Denton.
Had a great experience at AutoNation USA in Denton. Met with Cody and his Sales Manager, Sam, and both were super helpful and easy to work with. Went in looking for a safe, reliable SUV for my family, and found the perfect one. I had been checking out similar cars at other dealerships, but I kept coming back to AutoNation because they had the exact color combo I wanted inside and out. The SUV drives great, the price was fair, and the whole process was straightforward. Cody and Sam were transparent the entire time and walked me through each step without any pressure. They kept their word the whole way, which I really appreciated. I?d definitely buy from AutoNation again and recommend them to anyone looking for a solid, reliable vehicle.

During New Year’s Eve on 12/31/2025, I purchased a 2025
During New Year’s Eve on 12/31/2025, I purchased a 2025 Lexus NX with under 4,000 miles at BMW of McKinney, and the experience was outstanding thanks to Steven Saroyan. I originally visited for a vehicle I saw online, but it was no longer available. Steven took the time to understand exactly what I wanted, walked me through several options, and helped me find the perfect SUV that fit my needs and style. He was incredibly patient, knowledgeable, and never made me feel rushed. He also ensured I received a great deal, and the entire process was smooth, fast, and stress‑free. I truly appreciate his professionalism and exceptional service, and I highly recommend him to anyone looking for their next car.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

No pressure No games Easy buy of a cash car.
I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.
