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.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I purchased a certified pre owned Nissan Rogue SL that I
I purchased a certified pre owned Nissan Rogue SL that I saw on their website. It was a very good price and Mike Sui was the internet sales agent and texted/talked with me over a couple of days while I decided if it was worth the 90 min drive up from Tyler. Happy to report that it was! Mike is super friendly as are the rest of the staff. The car was as advertised and the process easy to purchase. Excellent trade in value and didn?t resort to deceptive or high pressure sales tactics. The only complaint I have is the wait time for the docs which they admitted took way too long because they were busy AND short staffed. All said I am very happy with them.

Excellent experience throughout
I have now been to this facility twice in the last two years (once to get an appraisal for a vehicle I ended up selling myself and now (Sept/2018) for a used vehicle purchase. Both times great, but this most recent was a shockingly easy process throughout with a very good person (Greg Leo) from CarMax. I had a specific need and the car was in CA (I am in TX) and Greg set up delivery, responded to any request I had, and kept me informed at all times of the stages. When I met him for actual purchase, I was in and out of the process (including a trade in) in 2 hours (prob could have done less but we got along well). This IS the way car buying should be done! Period. Great people, great business model. I also used CarMax financing with zero issues (excellent credit) and there is no pressure involved whatsoever (it is built into their process).

We had a straightforward, no hassle, seamless car buying experience at Ewing. Our salesman, Clayton, made the entire process easy for us from trading in our ?problem vehicle? to finding us the exact car we were looking for and having it delivered promptly. There were no salesman tricks, no hidden fees and no pushes to purchase extras we didn?t need. All around great experience. Highly recommend!

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.
