Awesome Buying Experience
My sales associate, Brian Safianow , could not have been nicer. He was a great listener and quickly assessed my needs. Dealership manager, Gary Venner, was involved in the process. The entire process was painless, fun and Brian provided concierge level customer service. Additionally, the technology department came to my home to provide a thorough tutorial on the different features of the vehicle. I am very pleased with the car,its many features and that subliminal new car smell. Park Place Lexus Grapevine treats their customers like royalty! This is my third experience with them, and I highly recommend them for the personalized, professional and exceptional service that they provide.

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!

Great car buying experience
We were very pleased with our experience. Don was very quick to return my initial communication. He explained the procedure for us meeting and had the car ready for our examination. All care was taken to insure the cleanliness and contamination free condition of the car. The procedure for purchasing the car was smooth and followed social distancing standards. We could not be any happier with how we were treated.
