Very well managed non pressure Lexus dealership that’s
Very well managed non pressure Lexus dealership that’s focused on my satisfaction first. We have been with the service department for 12 years and could not be more satisfied with experience and the loan cars!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Highly recommend the service team at Pat Lobb Toyota. Scheduling and drop off are simple and quick. The service advisers are right on top of getting my car into the service department and completed the work faster than I expected. And the coffee is good.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

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.

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).

Great Experience
This was the best car buying experience I’ve been through. Everyone I met, spoke to and met at Go Luxury Auto Group was friendly, professional and answered every question I had. The experience was effortless. Buying a car as a woman can be difficult. Sales reps are often condescending and don’t give you the time you need. Go Luxury Auto Group made me feel important every step of the way. Bryan is doing a phenomenal job and if you’re thinking of purchasing a luxury vehicle, this is the place to do it.

I give 5+ stars to this dealership.
I give 5+ stars to this dealership. We accompanied our granddaughter to purchase her first car. Kim was the sales associate. She was awesome…no pressure, answered her questions, and helped her to get payments that were affordable. She found just the car that was best for her, with the help of Kim, at a competitive price. Everyone was so helpful and the finance department explained the paperwork in a way a first-time car buyer could understand. I definitely recommend Autos of Forney!

Fantastic experience.
Even in these trying times they made the whole experience easy and painless. From our sales agent Trent to the financial guru Brian, everyone was friendly and helpful. They are 96 miles from us and I would not hesitate to make the trip again if they have something I want. We'll worth the trip.

We had a straightforward, no hassle, seamless car buying
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!

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.
