Pechemoacha!
Pechemoacha! Perfect loves it. Chill out Chelo is ecstatic about it, Mon knows no Virginia Slims are allowed in it, and Maria is busy making enchiladas. Bachas are bachas, and are having trouble crossing the chalk lines to come see it, but like how it?s described to them. Everyone loves it.
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!

We had a great experience with Bill Luke Chrysler Jeep
We had a great experience with Bill Luke Chrysler Jeep Dodge RAM. We specifically worked with Jay, Matthew, and Steve through out the process of our vehicle purchase. Excellent customer service, kind, responsive, and friendly team members. They ensured our needs were met and left a positive lasting impression of the dealership.
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 Experience
I had a great buying experience at Earnhardt Hyundai. Colin Fritsche was my sale person and I highly recommend you ask for him if considering a Hyundai.
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.

Nice Services.
Nice Services. I love there Services.As an avid car enthusiast, purchasing the was a decision I made after months of research and anticipation. Now, after driving it for several weeks, I can confidently say it has exceeded all my expectations. First impressions matter, and the sleek exterior design of the certainly grabs attention. Its aerodynamic curves and stylish accents give it a timeless appeal that turns heads wherever I go. The attention to detail in the craftsmanship is evident, from the precision of the body panels to the quality of the paint finish.
Best truck we have owned!

We have purchased several vehicles from Tamer at Liberty GMC. He is an amazing salesperson and we continue to go back as he provides us with the best experience. He is a knowledgeable, friendly and no pressure person. I would definitely reach out to him for all your automobile needs. Thenl dealership also has the best finance department we have dealt with by far. Would recommend Tamer and Liberty GMC to anyone in the market for a vehicle.

I recently purchased a 2025 Chevy Traverse, and I couldn't be happier with the outstanding service I received from the team at Courtesy Chevrolet. From start to finish, the experience was exceptional!!! Jackson, my sales person, was incredibly knowledgeable and attentive. He took the time to understand my needs and preferences, ensuring that the Traverse was the perfect fit for me. His expertise and friendly demeanor made the buying process smooth and enjoyable. Miguel in finance was a true professional, guiding me through the financing options with ease. He made sure I understood every detail and helped customize a plan that worked best for me. Miguel's commitment to customer satisfaction was evident in every interaction. Jessie in parts and accessories went above and beyond to help me personalize my new vehicle. His suggestions were spot-on, and she ensured that everything was ordered and installed promptly. Overall, the team at Courtesy Chevrolet exceeded my expectations with their excellent service and attention to detail. I highly recommend them to anyone in the market for a new vehicle. Thank you to Jackson, Miguel, and Jessie for making my purchase a memorable and pleasant experience!

It all centers around Trudy, my salesperson .
It all centers around Trudy, my salesperson . She was persistent and didn?t give up on the sale. I didn?t think we were going to buy from Yates even though the Yukon XL was our favorite of the Suburban and Expedition Max. Trudy really kept coming at us trying to make it work . Finally for me , it was Saturday when she sent me videos and said ? This is the one you drove. I know you and your wife liked it . It is here for you . Let?s make a deal!? Even later in the day on Saturday , I had already test driven another Expedition and Suburban with a diesel . I was not planing on stopping back at Yates but I was driving by on I10 and thought of Trudy?s videos she sent me. .I said , why not , she tried , let?s see. Even after I made a decision on the Chevy Suburban , ( only because it had a diesel ) but the Yukon XL was my favorite and Trudy was the most personable and persistent . Honestly , I was not the happiest with the numbers, everyone else gave me a little more for my trade BUT I liked your Yukon XL the most and we bought it . Also , it has to do with the Trudy being persistent . Even at the dealership getting ready to buy , I was having second thoughts and Trudy sat with me , and we talked while I waited . I almost walked out before the paperwork was ready . . But i really loved the Yukon XL. It had so many features I liked compared to the Suburban and Expedition. So Trudy?s customer service and I really liked the Yukon XL were my reason for sticking to it . Thank you Trudy . In addition , thank you Ramon , the fiance guy, he was patient in signing the paperwork . We were waiting for my wife who was on duty with the Fire Department. Another thing Trudy did right !! There was some issues with my wife at work and trying to sign the paperwork . Liability with me taking the Yukon XL home . Trudy was doing everything she could so i could take it home that night . Again , thank you Trudy !!

Fantastic Experience
This is my 3rd new car from Coulter, that in itself says volumes. Allen was great as always, our 2018 Terrain is wonderful and sits nicely next to the Acadia Limited I bought the last time. I highly recommend Coulter to anyone wanting to purchase their next vehicle.

Noticed some of the reviews on here for Rollit motors are not good. My husband and I have purchased two vehicles from this dealership and we only have good things to say. We worked with Jaime the two times he was great honest, available and offered great customer service. The two vehicles purchased are still in perfect conditions. I highly recommend.

My lease was up on a few months and this particular
My lease was up on a few months and this particular morning when I was driving to work there was a loud grinding noise coming from under my truck. So, I called Ashley in service and told her I would be bringing my truck in this afternoon. As always she greeted me with a big smile. When I explained the issue and about my lease being up soon, she introduced me to Adrian. From that moment he had everything under control. He asked me what I was looking for and what I was willing to pay. He spoke to a service writer, came out with numbers I was happy with, showed me a truck I asked for and the deal was done! Adrian went above and beyond. from the storage boxes under the rear seats to the safe in the center console. He even cut off my trailer hitch lock on Saturday for me. I Adrian and Ashley a 10+!!! GREAT JOB!
