They addressed my concerns in fast and effective way.
They addressed my concerns in fast and effective way. They were very helpful and took care of the problem very quickly. I have used this dealer before. The service is top notch.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

From the minute I hit submit, the replies I received from Trong Huyhn were prompt, to the point, polite and informative. I am one who hates buying cars, but Trong made me believe in the "Sewell Experience"
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.

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.

I was considering trading in my 2013 Mini Cooper even though I was having no problems and had low mileage. Went to Mini of Dallas and found one of the few 2025 convertibles. The staff was great, good pricing and no pressure. Low interest rate with the purchase of a new vehicle. Would recommend this dealership.

Great customer service!
Great customer service! Becca, my sales rep, was amazing. And Charlie, my finance guy, also did a fantastic job locking me in a deal that exceeded my expectations. I just drove my new Silverado to San Antonio and it handled like a dream! Way better than my old F150?

I was asked when I needed my truck back, I alex for 2pm. I never got a call, and when I went to the dealership at 3pm because u didn't get a call back, I was told my recall was not done and it would be 45 minutes longer. Very disappointing the lack of communication. There service department was slow and I never got av return call. I was not able to wait so had to take my truck. I would continue to go to Ewing but they will not take the service plan I bought from freeman when I purchased my truck. Keep in mind we've purchased five trucks from freeman in the last two years.
