Used 2020 GMC Sierra 1500 trucks for sale near Prosper, TX

The customer service was excellent and the service was fast. This is my first experience but it will not be my last. Thank you Clay Cooley.

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!

I purchased an SUV with Samuel Dixon. He was so awesome to work with and the sales transaction went smoothly. Sam and the team were straightforward. I look forward to purchasing again in the future. In the past, I've been to different dealerships, and I was tired of their deceitful tactics.

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.

Very easy to get appointment. My Service Advisor was great, kept advised to my vehicle. When I picked up my vehicle it was washed and clean. They did a great job for me. This is a great dealership and I would higly reccommend this dealership.

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.

I recently purchased a 2020 Mercedes G550 from Top Line Auto, and I couldn’t be happier! The car is absolutely phenomenal—every detail exceeds my expectations. The service I received was exceptional, going above and beyond to ensure a seamless experience. If you’re in the market for a vehicle, I highly recommend Top Line Auto. They truly deliver excellence in both cars and customer care!

Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

Excellent car buying experience. They had what i wanted and got me a deal on a 2016 mustang gt. I love mustangs. This is my fourth one.

Adam was incredibly helpful he listened to everything I needed and provided exceptional advice and service. I highly recommend going to Adam!

I went to buy a cash car. I had a price range to follow. I looked at a Lexus 07 LS460. I was helped out in getting a deal for this car by Jesse. I had some some request to be addressed first, to make me feel better about the deal. I saw they where all made. Maybe not to a high standard but they were done. The whole process felt easy with no pressure. I never believed Jesse was playing games with me. Ever. All in all he sold me a car I wanted and at the price I wanted. What more can you ask for? It's a 07. It's got issues. Yes. It's a used car but the buying experience was never an issue. Would I go back to buy another one? Yes. Will I tell a friend? Yes. I just recommend you do your own research on the particular car your looking at. I did not and still got a good deal. Ask for Jesse.

Several sales personal where informative and knowledgeable in customer service. I didn’t purchase a vehicle but will give Vanguard the first choice at sales.

Best car buying experience I've ever had. Jason was so helpful with the finance and sales part. We were in and out in less than an hour. I was worried about hidden fees like the other dealerships i shopped at, but Dallas cars have none. They earned a customer for life

Best experience I’ve had and I’ve had several in my life. I also had several prior to buying this vehicle. Kariel Nieves was my sales guru. Totally awesome gentleman and knows his stuff. Great attitude and huge knowledge of all things Lexus. Good communicator and worked with me to get my scheduled test drive and had everything ready. A++++++++ I’m sure they have many excellent associates but I’ll only work with Kariel from now on. Top noche.

Lots of Cars available Easy to maneuver web site prices are reasonable . I did not purchase at this time but would consider I have a later time

Got in touch with me very quickly when I messaged. Very easy to work with and the truck I bought was priced to move. Easy buy and great experience overall!

I have purchased cars from Sewell in the past and once again, their service and inventory is SUPERIOR! We are so happy with our vehicle and the overall experience!

Great place to get a car great staff wonderful results best in Dallas 💯 would recommend more people to go and buy!

Nice sales people. Easy to work with, but would not move on the price of the car.
