A Great Transaction with Ewing Subaru
Angel at Ewing Subaru made our purchase very easy. I looked at cars for my daughter from Corpus to Dallas, focusing on Houston since I live there. Ewing offered the best value, enough better to justify flying to Dallas for the purchase. Angel took care of the transaction electronically, and even delivered the car to Love Field to complete the deal. He met me at customer arrivals, we signed a few papers, and I was driving to Houston before security even had a chance to ask us to move along. A perfect buying experience!

I?ve never been disappointed when taking my 2023 Santa Fe
I?ve never been disappointed when taking my 2023 Santa Fe to their service dept. I?ve only had to have oil changes and servicing so far. I did buy a new set of tires at the dealership, and it was efficient and a pleasureable experience.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Cowboy Toyota Wants To Serve You
My experience at Cowboy Toyota was pleasant, professional but most importantly profitable. I was able to finalize a deal and drive away in a new vehicle of my preference. They are easy to talk to and they make an effort to satisfy you as a guest as well as a customer. I feel assured in terms of recommending Cowboy Toyota to family and friends because I feel confident they will achieve the results they are looking for as it relates to buying a new car.

I recently purchased a vehicle from Top Line Auto, and the experience was outstanding from start to finish. The team was incredibly knowledgeable, attentive, and genuinely committed to making sure I found the perfect car. They went above and beyond in providing detailed information about the vehicle, including mileage, Carfax history, and available warranties, which made me feel confident in my purchase. The process was smooth and stress-free, with no pressure or rush to make a decision. I also appreciated their willingness to work with my schedule and accommodate my needs. The level of customer service at Top Line Auto is truly exceptional, and I would highly recommend them to anyone looking for a quality vehicle and a hassle-free buying experience.

First Class Experience
Okay, this is an older facility without all the excesses that are in so many new dealerships. I believe that the lower overhead results in a lower price for the customer. My sales person, Lou Margetis, was outstanding in answering my questions, making sure that I got to look at and drive all the vehicles that I was interested. Working with Lou, and Timothy Goodman, the New Car Director, I got what I thought was an excellent price on a new Kona SEL Plus, much better than any other Hyundai dealership. Then, Timothy Goodman made sure that I was taking advantage of all the Hyundai specials, and another $1000 came off - wow, now I had a deal that I could not refuse. I bought the Kona and drove it home that evening. Then, a few days later, Katarina, their customer relations specialist followed up, and was very helpful in answering a few questions and was sincerely interested that everything went well. It was an awesome experience, and I highly recommend this dealership. Finally, I was also very impressed that this dealership was taking the Covid-19 issue very seriously and making sure everyone was safely taken care of.

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!
