This is our 5th car purchased and we have always been happy with the customer service. We will continue to purchase future cars. Thank you
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!

Good Dealership
Thanks to Alfonso I purchased my long awaited Ford Maverick. Alfonso was very helpful and patient with questions I had and offered after purchase assistance with anything else I needed. Also to the finance guy (sorry forgot his name). He was really helpful as well.
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.

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!
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!

Look for Jaime
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.
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 new car buying experience
We bought a new Mazda CX-5 at this dealership last weekend. The Sales Consultant, Lauren Schnebly, was a true professional from the time we met her to the moment we drove off with the new car. It was the best new car purchase experience we've ever had.

Shop smarter Not Harder
To me these reviews all sound like everyone wants what they want this is a business that’s selling used cars a tip to help new buyers. You are given a 500 mile or 15 day warranty take the car you buy down to the original dealership or any mechanic have them do a over all inspection if anything is wrong with the car that the warranty covers take it back to the place you bought it from and they are legally obligated to fix it at their expense not yours because it falls under the warranty also make sure you buy GAP INSURANCE AND ANY OTHER EXTENDED WARRANTIES REMEMBER THIS IS YOUR MONEY AND INVESTMENT!!!!! Hope that helps anyone out on here or anyone looking for a car. I AM NOT A LAWYER & THIS INFORMATION IS BASED ON A PERSONAL EXPERIENCE…..

We have purchased several vehicles from Tamer at Liberty
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.
