Tyler provided the smoothest purchase process I have
Tyler provided the smoothest purchase process I have experienced. Not only was respectful, listened to me without interuption, and made me feel very comfortable as if I have known him a very long time. When I talked to Tyler before going to the dealership, and let him know what I was looking for, he had a vehicle ready for me to look at and test drive. After the test drive Tyler showed me the vehicles features, explaining them one by one and while he was explaining I realized this was the vehicle I was looking for. We went back to his office, completed the paperwork and I drove off. I was suprised the purchase only took a few hours compared to past purchased that took all day to make. If you are looking to purchase a Ford go see Tyler he will take excellent care of you and find you the exact vehicle you are looking for.
Our 2021 Terrain SLT is really a nice auto.

I’ve had the privilege to work with Cesar Marques
I’ve had the privilege to work with Cesar Marques (Service Director) and his customer service support staff on a few different occasions over the last couple years regarding our 2021 Hyundai Santa Fe. Mr. Marques has exceeded our expectations with his excellent customer service experience , his professionalism and his ability to relate to the customers needs. I consider him a major asset to the Hyundai family. If I do decide to purchase another Hyundai down the road, it will be a direct result working with of Mr. Marques. Thank you, Larry Ort
One of the best looking suv's on the road. Highly
Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

This was a positive experience.
This was a positive experience. Adam was terrific as a salesperson and very helpful in setting the car up for me. I will refer others to him, and Liberty, if the chance arises,
Grea4 mileage and comfort
Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.

Greenway Kia North serviced my 2022 Kia Telluride on
Greenway Kia North serviced my 2022 Kia Telluride on 9/12/25. The service tech registered my car as soon as I arrived at 7:50 am. After waiting an hour, Kia provided a shuttle to take me home. When the service was completed, Kia called, and I order the shuttle. After waiting for the cashier to come, I paid what I thought was a reasonable bill. But no one bothered to inform me if the recalled power seat switch was fixed or part ordered or what. One air pressure sensor has been alarming regularly for the past three months, but the tech could not get it to alarm during the service - so, I will just have to put up with it. Kia North is a nice place, and the staff is friendly enough but were not real informative in my case.

Jasmine Robinson was my service rep, she was great, she kept me informed of services needed to vehicle & prices changes. Customer service is key when your spending your money. The mechanic did a complete video while inspecting my car & showed filters, tires, wiper blades. This was the best experience I had there in a while.

⭐⭐⭐⭐⭐ Outstanding Experience at Easterns Automotive
⭐⭐⭐⭐⭐ Outstanding Experience at Easterns Automotive (Laurel) – A Shoutout to Mr. Lorenzo Joseph! From the moment I walked into the Easterns Automotive Laurel location, I knew I was in good hands. The dealership itself was clean, organized, and had a welcoming atmosphere—but what truly made my experience exceptional was the customer service provided by Mr. Lorenzo Joseph. Mr. Joseph went above and beyond to ensure my car-buying experience was seamless and stress-free. From the initial greeting to handing me the keys, he was patient, knowledgeable, and genuinely invested in helping me find the right vehicle. He took the time to understand my needs and budget, provided expert recommendations without any pressure, and answered every question I had with honesty and professionalism. What really stood out was his attention to detail and the way he treated me like more than just another customer. His calm demeanor, transparency throughout the process, and commitment to making sure I left happy made all the difference. In an industry where great customer service can be hit or miss, Mr. Joseph is a true standout. If you’re looking for a new or used vehicle and want a team that values integrity and top-tier service, I highly recommend Easterns Automotive in Laurel—and be sure to ask for Mr. Lorenzo Joseph. He turned what is often a stressful process into a truly enjoyable one. Thank you, Mr. Joseph, for your stellar support!

We drove 4 hours to buy a used car from Jeff Wyler
We drove 4 hours to buy a used car from Jeff Wyler Eastgate auto mall . Very good location in Cincinnati,Ohio ,well worth the drive, our sales agent , James Williams was very professional ,courteous ,informative and friendly. Mike Broughton in the finance department was very friendly also. Both young men treated us with respect not pushy like some people at dealerships that we had visited before ,So if you are looking for a New or Used vehicle , it would be worth your time to make the trip to Jeff Wyler Eastgate Auto Mall

I have been visiting the Coral Springs Buick GMC since
I have been visiting the Coral Springs Buick GMC since 2016, and what keeps me coming back is the excellence in customer service. For a while, I debated whether to purchase another vehicle. However, when I recently decided, the sales staff (Pierre Jean-Baptiste) and his supervisor (Kevon Logie) went above and beyond to ensure I received the vehicle I desired, helped me problem-solve when there was a delay with the bank payment, verified the rebate through ID.me, etc. For me, it was the level of patience, care, and understanding that made me leave with a purchase, of course, and reminded me of the experience and feelings of when I purchased my very first GMC. For context, it took me almost an entire week to buy the vehicle, not because of their failures, but because I wanted to make sure my son received my current GMC as his first GMC. Costco auto-buying and my bank suggested other dealer locations. Still, I was adamant about going anywhere else but this location, because I always leave feeling like a VIP because of the service. While I am giving out accolades, I definitely want to recognize the service department. I would not keep buying GMC if it were not for its impeccable service. I wish to acknowledge and thank Luis, who has had to put up with my demands, gripes, and frustrations since 2016, but has made sure my vehicle keeps running, even when I drove it from Florida to Virginia. I also want to thank Alex ~ I call him my after our mechanic with sooo much patience and understanding, which helps me all the time before closing with a flat, some diagnostic issue that comes up... I cannot thank Coral Springs Buick GMC enough for embracing me every time I show up as a VIP, and I will forever tell my friends to go there to get their vehicles.

Cody did a great job, as always.
Cody did a great job, as always. When they installed my new battery, the after factory remote starter they installed stopped working. He tried to get ford to replace after only 3 years. They wouldn’t. They would split it but it had doubled in price. Not using a Ford product that quit working. Cody tried his best.
