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.
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 had an outstanding experience at Toyota of Rockwall
I had an outstanding experience at Toyota of Rockwall during the maintenance service for my 2024 Toyota Tundra, and I want to give a special shoutout to Kasey for her exceptional customer service. From the moment I arrived, Kasey was friendly, professional, and extremely attentive. She kept me informed throughout the entire process, clearly explaining what was being done and making sure I was comfortable with the timeline. It’s rare to find someone who takes that level of care in making sure the customer experience is smooth and stress-free. My truck was serviced efficiently, everything was handled exactly as promised, and the communication was top-notch from start to finish. Kasey truly made the whole experience seamless and exceeded my expectations. If you’re bringing your vehicle in for service, I highly recommend asking for Kasey. Toyota of Rockwall has earned a loyal customer thanks to her outstanding service.

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 online and scheduled a test drive for the next morning. When I arrived, Xavier Perez met me and had the vehicle ready for me. After I decided to purchase the vehicle, Xavier helped me transfer some items from my current truck to the new truck. He facilitated with the service shop to have my NFab boards removed and put on my new truck and even put on my new tags and removed the license plate holder and hitch holder. Xavier was professional, seasoned and knew what to ask and how to make my purchasing process go smoothly. He is an excellent example of a veteran sales professional at Young Chevrolet
