Best experience I’ve had and I’ve had several in my life.
Best experience I’ve had and I’ve had several in my life. I also had several prior to buying this vehicle. Kariel Nieves was my sales guru. Totally awesome gentleman and knows his stuff. Great attitude and huge knowledge of all things Lexus. Good communicator and worked with me to get my scheduled test drive and had everything ready. A++++++++ I’m sure they have many excellent associates but I’ll only work with Kariel from now on. Top noche.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Update, I was quickly contacted by the GM who promised to make good on the car by either getting rid of the smell or take the car back.

The car buying experience usually elicits a fair bit of anxiety from me, but I have to say 5 Star Subaru of Grapevine made my car purchase pretty painless. They are a business and they have to make money, I get that, but "Chief" (my sales consultant) was super easy going and I felt no hint of pushiness or pressure. We worked out a deal I was happy with and I drove away feeling good about it.

My husband and I put off looking for a new car for a very long time. We finally decided we would replace the car that we currently had with a newer model. We ended up with a 2024 Chrysler Town & Country that looks and drives brand new. Our salesman was Guillermo Villanueva and the manager was Juan Tapia. They didn’t pressure us. It was the easiest big purchase buy that we have ever made. These guys are 100% professional and 100% pleasant. We will definitely work with them again on our next car buy. Big thanks to Guillermo, Juan, and the folks at Classic Chevrolet in Grapevine! C & M Wilk
